Question

A stone is dropped from the top of a towerand it crosses the midpoint after t seconds further time needed by the stone to reach the ground is

Answer 1

Answer:

t(√2 - 1) sec

Explanation:

h/2 = gt²/2

h = gT²/2 , T = total time

T²/t² = 2 , T = t√2

further time needed by the stone to reach the ground is

T - t = t(√2 - 1) sec
