Question

a ball weighing 15 Newton falls from a height of 30 M calculate the energy that when it is at rest what is the form of energy it experiences but it reaches the ground considered g 10m per second square

Answer 1

At the highest point of the ball Journey, velocity of the body will be zero.

At that Point, the total energy of the body will be in the form of Potential Energy.

Therefore, Total energy of the body at highest point = mgh

E = mg × h

mg is the weight of the ball, which is 15 N as given in question,

Therefore,

E = 15 × 30

∴ E = 450 J.

Hence, total energy of the body is 450 J.

Hope it helps.
