A particle of mass'm' is projected with ...

A particle of mass`'m'` is projected with velocity `v_(0)` at an angle `'alpha'` with the horizontal. The coefficient of restitution for any of its impact with the smooth ground is `e`.

Find total time taken by the particle before it stops moving vertically?

A

`T = (2v_(0)sin alpha(1 + e))/(g(1 - e))`

B

`T = (2v_(0)sin alpha(1 - e))/(g(1 + e))`

C

`T = (2v_(0)sin alpha)/(g(1 - e))`

D

`T = (2v_(0)sin alpha)/(g(1 + e))`
