A ball is thrown up at an angle with the horizontal. Then the total change of momentum by the instant it returns to ground is

A

Acceleration due to gravity X total time of flight

B

Weight of the ball X half the time of flight

C

Weight of the ball X total time of flight

D

Weight of the ball X horizontal range

Text Solution

Verified by Experts

The correct Answer is:
C
Change in momentum = `2mu sin theta`
`rArr 2mgu (sin theta)/g = mg xx (2u sin theta)/g`
`rArr` weight of the ball `xx` total time of flight.
