Question

If a stone projected from ground takes 4s to reach the top most point of its trajectory then time of flight

Answer 1

Time of flight :

This is the time taken by an object projected vertically upwards to reach the maximum height and fall back.

Given that this body experiences equal acceleration due to gravity throughout its motion, the relationship below follows.

Time of flight = Time to reach maximum height × 2

From the given relationship, we can obtain the time of flight as follows :

Time of flight = 4 × 2 = 8

= 8 seconds.
