Question

You drop a 5 kg ball from a height of 2 m. Just before it reaches the ground, what type of energy does it have?​

Answer 1

At the height of 2 m, K.E is 0 J and potential as mgh=5*2*10=100 J. Hence at lowest height, the Potential energy should be converted into the kinetic. Hence, the KE of the ball should be 100 J just before touching the ground.
