Having gone through a plank of thickness h, a bullet changed its velocity from `V_(0) " to" v` . Find the time of motion of the bullet in the plank , assuming the resistance force to be proportional to the square of speed of bullet .

Text Solution

Verified by Experts

The correct Answer is:
`t = (h(v_(0)-v_(f)))/(v_(0)v_(f)ln (v_(0)//v_(f)))`
