A particle of mass `m` moving with speed `u` hits a wedge of mass `M` – InterviewSolution

InterviewSolution

1.	A particle of mass `m` moving with speed `u` hits a wedge of mass `M` as shown in figure. If coefficient of restitution is `e` and friciton can be neglected, then find the speed of the wedge with respect to ground just after the collision.
Answer» `((1+e)m*usin^(2)theta)/(M+msin^(2)theta)`
