A body is projected obliquely from the ground such that its horizontal range is maximum. If the change in its linear momentum, as it moves from half the maximum height to maximum height, is P, the change in its linear momentum as it travels from the point of projection to the landing point on the ground will be:

Options

A. P
B. `sqrt(2)P`
C. `2P`
D. `2sqrt(2)P`

Answer

d

Explanation

`P=(mv sin theta)/sqrt(2).P'=2mv sin theta`
