If a 1,500 kg car and a 4,000 kg truck were moving at the same speed down a steep hill, what statement is false?


A: The truck will have greater kinetic energy and be more difficult to stop.



B: The car has less mass, and therefore less kinetic energy, when compared to the truck.



C: Both vehicles would have their greatest kinetic energy as they reached the base of the hill.



D: The car's potential energy will be greatest when at its highest speed.

Answers

Answer 1

Answer:a

Explanation:because if you have a bigger or heavier truck I can be harder to stop then a car

Answer 2

The car kinetic energy not potential energy is greatest when at its highest speed.

Kinetic Energy:

It is the energy of the object which is due to the motion of object. The formula of kinetic energy is

[tex]\bold {KE = \dfrac 1{2} m v^2}\\[/tex]

Where,

m - mass

v - velocity

The kinetic energy of the object is directly proportional to the mass of the object and square of the velocity of the object.

So, A, B and C are correct statement.

Therefore, the car kinetic energy not potential energy is greatest when at its highest speed.

what would happen if 15 joules of work is done on an object that has 90 N of force applied to it

Answers

Answer:

The magnitude of the force is given by F = ma = (10)(5) = 50 N. It acts over a distance of 20 m, in the same direction as the displacement of the object, implying that the total work done by the force is given by W = Fx = (50)(20) = 1000 Joules.

First of all, scientific naming, also known as Biomial Numiclature, is a formal system of naming a specific species or living thing. We all use the scientific naming because we need to work together in most problems as a team and figure out what species an animal or species is.

Explanation:

Just so you know, if we never worked together, our goals would be a lot harder to accomplish. For example, I rn 7 miles yesterday with my mom. If my mom wasn't right there by my side while we were doing it, it would be a lot harder and I would've probably done a lot worse or less mileage.
