Two bodies are thrown at the same time a...

Two bodies are thrown at the same time and in opposite directions and with an equal velocity `v_(0)` at angles `alpha_(1)` and `alpha_(2)` to the horizon. What is the velocity with which the bodies move relative to each other -? What will be the distance between the bodies be after time t elapses ?

Text Solution

Verified by Experts

The correct Answer is:
`[2v_(0) sin.( (alpha_(2) - alpha_(1))/(2)), 2V_(0)t sin ((alpha_(2) - alpha_(1))/(2))]`
