A boy weighing 40kg makes a high jump of 1.5m
a) What is his kinetic energy at the highest point?
b) What is his potential energy at the highest point?
Mass of boy, m = 40 kg
Height, h = 1.5m
Acceleration due to gravity, g = 10 m/s^2
a) At highest point velocity, v = 0
Therefore, KE = 0
b) PE = mgh = 600J
