Question

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.

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

$\bold {KE = \dfrac 1{2} m v^2}$

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.
