Question

A stone is dropped freely from the top of a tower and it reaches the ground in 4 s. Taking g = 10 m s-2, calculate the height of the tower.

Answer

g = 10 m s^-2

Time (t) = 4 s

Initial Velocity (u) = 0

h = ut + 1/2 × gt²

= 0 × 4 + 1/2 × 10 × 4²

= 0 + 5 × 16 = 80 m

Hence, the height of the tower is 80 m
