We will use the following equation of motion.
S = Ut + 0.5gt²
Where S is the height, g the gravitational acceleration and t the time and U the initial velocity.
In the first case U = 0and hence S is :
S = 0 + 0. 5 × 10 × 9 = 45m
In the second case U is 5m/s and hence height is :
S = 3 × 5 + 0.5 × 10 × 9
S = 60M
The difference in height is thus :
60 - 45 = 15m
