Question

An object is failing freely from a height x. After it has fallen a height x/2,it will possess:
​

Answer 1

Explanation:

Correct option is

C

Half potential and half kinetic energy

Since the ball is in free-fall, the only force acting on it is gravity. Therefore, we can use the principle of conservation of mechanical energy - initially the ball has potential energy and no kinetic energy.

After it has fallen a height

2

x

it will possess half potential and half kinetic energy.

Hence, option C is correct.
