Question

A body is fired vertically upward. At half of the maximum height, the velocity of the body is 10 m/s. What is the maximum height raised by the body ?

Answer 1

At half the maximum height the initial velocity to now reach maximum height is :

10m/s

The formula for getting max height is :

Max height = u²/2g

Let g = 10

Max height from half the height is :

10²/10 = 10m

This is half the total height that should have been attained.

Therefore the maximum height attained is :

2 × 10 = 20 m
