Two identical vehicles are moving with same velocity `v` towards an intersection as shown in figure. If the collision is completely inelastic, then

Text Solution

Verified by Experts

The correct Answer is:
6
The collision is perfectly inelastic
Hence , `intNdt = msqrt(2gh)`
and the linear impulse
`int mu Ndt = mv`
`mu m sqrt(2gh) = mv`
`v = mu sqrt(2gh)`
