The mass of a ball is 20g and its height is 8m, calculate (a) the potential energy of the ball at F (b) the kinetic energy when it has a velocity of 2m/s. (c) the velocity just before it touches the ground ( take s = 10m/s2)

The potential energy (PE) of an object is given by the formula:

PE = mgh

Where:
m = mass of the ball = 20g = 0.02 kg
g = acceleration due to gravity = 9.8 m/s^2 (approximate value)
h = height of the ball = 8 m

So, the potential energy of the ball is:

PE = 0.02 kg x 9.8 m/s^2 x 8 m
= 1.568 J (joules)

Therefore, the potential energy of the ball at height F is 1.568 J.
