Question

A ball with 100 J of potential energy is released from a height of 10 m what will be the kinetic energy of the ball at 5 m

Answer 1

Answer:

50J is the kinetic energy of the ball at 5m

$100j = mgh \\ 100 = m \times 10 \times 10 \\ m = 1$

potential energy when h = 5m

Explanation:

$1 \times 10 \times 5 = 50j$

we know that the total energy is conserved

the kinetic energy at 5m is

total energy- potential energy at that point = kinetic energy

100J - 50J= 50J
