A body of mass m is thrown straight up with a velocity Mq. Find the velocity u' with which the body comes down if the air drag equals `cu^(2)` where c is a constant and u is the velocity of the body.

Text Solution

Verified by Experts

The correct Answer is:
`[u' = (u_(0))/(1+(cu_(0)^(2))/(mg))^((1//2))]`
