What is the net force needed to accelerate a 1 kg textbook with an acceleration of
4 m/s2

Answers

Answer:

4 N

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question

mass = 1 kg

acceleration = 4 m/s²

We have

force = 1 × 4 = 4

We have the final answer as

an amusement park ride has two identical carriages that revolve around the center of the ride’s axle, as shown in the figure. both carts travel at a constant tangential speed at all points along the circular path. at what position is the total mechanical energy of the cart-cart-earth system at its maximum value?

Answers

The principle of conservation of energy allows to find the result for the mechanical energy of the system is:

Mechanical energy is conserved at all points, therefore at all points it has the same value.

Mechanical energy is defined by the sum of the kinetic energy and the potential energies.

            Em = K + U

In the principle of energy conservation, it establishes that energy cannot be created or destroyed, it is only transformed, in the case of no friction, mechanized energy is conserved at all points.

They indicate that the system is rotating, which is why it is subjected to a force that expends its energy in changing the direction of the speed to keep the system in rotation, so the speed of the system remains constant.

          Em = K = ½ I w²

Consequently, using the principle of conservation of energy we can find the result for the mechanical energy of the system is:

Mechanical energy is conserved at all points, therefore at all points it has the same value.

An object on Earth weighs 600 N and on Mars 100 N. If its mass on Earth is approximately 60 kg what is the mass of the object on Mars?

Answers

Answer:

I think its

10 kg

plzz plzz plzz. mark as brainliest

If the mass of an object is approximately 60 kg on earth then its mass remains the same on Mars which is 60 kg because mass does not change from place to place.

What is mass?

Mass in physics is a numerical representation of inertia, a fundamental property of all matter. What a body of matter is fundamentally is the resistance it offers to a change in its speed or location brought on by the application of a force. The more mass a body has, the less of a change a force exerts results. The kilogram is the unit of mass in the International System of Units, and it is defined by Planck's constant as being equal to 6.62607015 × 10⁻³⁴ joules second (SI).

According to the question, the weight of an object depends on gravity which is different from place to place so weight also varies from place to place but the mass is constant everywhere it does not change. So, if the mass of an object is 60 kg on earth then it remains the same on mars also.

A: 0N
B: 50N
C: 100N
D: 150N

Answers

Answer: 0N

Explanation: Hope this helps :)

last time i wrote the wrong answer for the wrong problem :)

For the constant speed, the resultant force on the plane is 0N. So, the correct option is A.

What is Force?

A force is defined as the parameter that can change the momentum of an object that can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or pull where force has both magnitude and direction, making it a vector quantity.

For above given information, the plane is moving at a constant speed. According to Newton's first law, the net external force on the aircraft due to the thrust generated by the propeller must be zero and air resistance is equal and in opposite directions to produce zero net force.

Thus, for the constant speed, the resultant force on the plane is 0N. So, the correct option is A.

. A small toy car having 300 grams of mass and going straight with an initial velocity of 13 m/s. When the toy car collides with an obstacle, a resistive force of 4 N acts upon it. The speed of the toy car reduced and reached 8 m/s. Draw its free body diagram and then find the time for the toy car to be into rest position?

Answers

The free-body diagram is attached in the image below. The time for the toy car to be in rest position is 0.6 s

From the given information:

The mass of the toy car = 300 g = 0.3 kgThe initial velocity (u) of the car = 13 m/sThe resistive force F_r acting on the car = 4 NThe speed of the car (v) = 8 m/s

A force is regarded as a push that causes an alteration in motion of an object within a specified distance. It is usually expressed by the formula:

Force = mass × acceleration

acceleration = Force/massacceleration = (4 / 0.3) m/s²acceleration = 13.33 m/s²

Using the first equation of motion for the time to bring the car to rest from it reduced speed of 8 m/s;

v' = v + at

since the final speed to bring the car in rest position is (0), then:

0 = 8 -  13.33(t)

13.33(t) = 8

t = 8/13.33

t = 0.6 seconds

In fact, I kept looking back to make sure I could retrace my steps. Looking back didn't work. All of the trees began to look the same, and nothing looked familiar. It wasn't until I finally decided to make my way back that I realized I was lost! I had gone much farther, and for much longer, than I had planned.The warmth that the sun had brought to the forest in the daytime was now quickly disappearing. My parents' warnings came racing through my head. What did they tell me to do if ever I got lost? Over and over they drilled into me, "The most important thing to remember is S.T.O.P.!" It's an acronym for sit, think, observe, and plan. I stopped, sat down on the forest floor, and pulled my knees in close. It was cooling off, and a light drizzle was dampening the forest. I was lonely and scared. I knew that to survive, I had to stay warm, and I needed to drink water. Before I got any wetter, I made a very crude lean-to from the nearby branches and foliage. I managed to collect a bunch of dry leaves for a mattress. It was dark now. I took off my T-shirt and wrapped it around my legs, pulled on my hoodie, and curled up on the bed of leaves.

Captain Henry was directing all of his strength to hold the steering wheel and control the ship. The waves were the size of mammoths, and the boat continued to fill with angry water. Captain Henry yelled at his fellow sailors to scoop out the water that was weighing down the ship, but the sailors could not work any faster. "We are sinking! We are sinking!" shouted the sailors.Captain Henry knew that they were in trouble. With little time to spare before the ship began to sink into Lake Superior, Captain Henry made an urgent call to his older brother. His older brother had helped him with everything from cuts to broken bones all of his life. He was a father figure to Captain Henry. Coincidently, his older brother was also the strongest, bravest, and most dedicated coastguard in Bayfield, Wisconsin. Luckily, with Lake Superior just north of Bayfield, Captain Henry's brother would hopefully be able to rescue them soon. Captain Henry began to desperately flash the emergency lights on the boat so that his brother could find him. In the distance, the sailors pointed to a boat coming their way and tooting its horn. As Captain Henry's brother arrived, he threw a rope to the sailors and pulled them to safety. Standing on the boat, wrapped in blankets, the sailors, Captain Henry, and his brother watched the ship sink. "All good things must come to an end," stated Captain Henry, sadly. "But, hey! Now, you can practice your diving again and go see your ship at the bottom of the lake," joked Captain Henry's brother.Both texts tell of a need to be rescued.
