If the forces exerted on a 2-kg object are 50 N east and 30 N west, what is the object's acceleration?

Answers

Answer 1

If the forces exerted on a 2-kg object are 50 N east and 30 N west, the object's acceleration is 10 m/s².

What is acceleration?

Acceleration is defined as the speed at which an object's velocity changes over time. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration.

To calculate acceleration we use formula

F = m x a

Given m = 2 kg

Net force = 50 N - 30 N

                = 20 N

a = F / m

a = 20 N / 2 kg

a = 10 m/s²

Thus, if the forces exerted on a 2-kg object are 50 N east and 30 N west, the object's acceleration is 10 m/s².

Angular velocity is the speed at which the angle between 2 bodies changed whenever an object rotated or revolvers around an axis. This displacements is depicted in the images by the angle firmed by a line on one body andar a line on the other.

Angular velocity can be defined as the Speed at which an item rotates or revolvers around an axis. The Greeks letter Omega (occasionally ) stands for angular velocity. The SI unit for angular velocity is radians per second because it is the expressed as an angle per unit of times.

Orbital speed increase with radius beacuse it is directly proportional to radius

a dog lifts a 0.75 kg bone straight up through a distance of 0.11 m. How much work was done by the dog ?

Answers

The work done by the dog is 0.81J.

What is work done?

Work done is a measure of energy expended in moving an object; most commonly calculated by multiplying the force by the distance.

It is said that no work is done if the object does not move.

The work done on an object is the amount of energy transferred to an object through work.

According to this question, a dog lifts a 0.75 kg bone straight up through a distance of 0.11 m. The force applied to break the bone must be calculated first as follows:

Force = mass × acceleration

Force = 0.75kg × 9.8m/s²

Force = 7.35N

Work done = 7.35N × 0.11m = 0.81J

Therefore, 0.81J is the work done by the dog.

if the sound wave lasts 4 seconds, how much distance did it travel? (please help me)

Answers

Answer:

A wave is a disturbance that moves along a medium from one end to the other. If one watches an ocean wave moving along the medium (the ocean water), one can observe that the crest of the wave is moving from one location to another over a given interval of time. The crest is observed to cover distance. The speed of an object refers to how fast an object is moving and is usually expressed as the distance traveled per time of travel. In the case of a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given interval of time. In equation form,If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s. On the other hand, if the crest of an ocean wave moves a distance of 25 meters in 10 seconds (the same amount of time), then the speed of this ocean wave is 2.5 m/s. The faster wave travels a greater distance in the same amount of time.

when the distance between two masses doubles, the strength of the gravitational force between them ―

Answers

When the distance between two masses doubles, the strength of the gravitational force between them is decreased by a factor of 4.

Gravitational Force:

Any two mass-containing objects are attracted to one another by gravitational force. Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive. In reality, everything in the cosmos is tugging on everything else, including you! Newton's Universal Law of Gravitation is what it is known. Admittedly, you aren't pushing on those other objects all that much because you don't have a very large mass. Additionally, items that are very far apart from one another do not clearly tug on one another. However, we can calculate the force because it exists.

It is given by,

                        [tex]F=\frac{GMm}{r^{2} }[/tex]

We can clearly evaluate from the above formula that

                       [tex]F[/tex]   ∝   [tex]\frac{1}{r^{2} }[/tex]

Answers

Answer:

Explanation:

One possible safety restraint or device for a motorcycle 4-wheeler or go-kart could be a roll cage. A roll cage is a structure that surrounds the driver and is designed to protect them in the event of a rollover or collision.

The roll cage would be made of strong, lightweight material such as steel or aluminum tubing. It would be attached to the frame of the 4-wheeler or go-kart and would extend upward to surround the driver's head and shoulders. The roll cage would also have additional bracing to provide additional support and protection in the event of a collision.

In the event of a rollover or collision, the roll cage would help to distribute the forces of the impact evenly around the driver, protecting them from the full force of the collision. The additional bracing would also help to prevent the roll cage from collapsing or deforming, providing additional protection for the driver.

In addition to the roll cage, the driver could also wear a safety harness or seat belt to help keep them securely attached to the vehicle and prevent them from being thrown out in the event of a collision. This would provide additional protection against the forces of a collision.

What is an average acceleration?The rate of change in velocity, or the change in velocity per unit time, is known as average acceleration. The square of the distance over time is used to measure acceleration. Hence, the unit of acceleration is known to be as m/[tex]s^{2}[/tex].

The further a listener is from the sound, the lower the pitch because the sound waves are more spread apart (lower frequency).

Answers

Car acceleration is 7.794 m/s2 and the average force F is 638.32 N.

Because the passenger is in the car, the passenger experiences the same velocity and acceleration as the car.

Linear impulse equals mass times a change in speed (Vf - Vi)

Initial velocity is Vi, whereas ultimate velocity is Vf.

When the passenger's mass,

m(mass), is 81.9 kg,

the linear impulse is 81.9 kg ×(4.1 - 0)

= 335 kgm/s.

F(average) = m × acceleration

Acceleration = Vf - Vi/ t

Acceleration= 4.1 - 0 ÷0.526

Answers

Answer:

The total distance covered is 3 km and the displacement is 2.24 km.

Explanation:

For the total distance covered by Anthony, we just add all of the distances.

1 km (going east) + 1 km (going east again) + 1 km (going south) = 3 km

Hence, the his total distance covered when he went to the pizza place is 3 km.

Solving for the displacement is a different matter. We cannot just add all of the distances. From analysis of the problem, Anthony traveled and formed a right triangle. He traveled 1 km east twice, making it 2 km east in total, then he traveled 1 km south.

When dealing with a right triangle with 2 sides given (for this problem the two sides are the 2 km east and the 1 km south), we use the Pythagorean Theorem.

Solution:

c² = a² + b²  (Pythagorean Theorem)

c will be the longest side of the right triangle

a and b will be the other sides of the right triangle

c = √ (a² + b²)

c = √ (2² km + 1² km)

c = √5 km

c = 2.2361 km ≈ 2.24 km

Therefore, the displacement of Anthony is 2.24 km.
