3. A particle of mass m moves vertically downward with velocity vi and strikes a smooth triangular block of mass 2m which is initially stationary. Assuming a coefficient of restitution e, find the velocities of the block and the particle immediately after impact. Hints . The restitution of two object in one-dimensional collision means, γ = ta-ta, where vang are the velocities after the impact and va, vb are the velocities before the impact, obeying the same positive direction ....

Object A of mass M is initially at rest on a flat, smooth
frictionless surface. Object B, which has twice the mass of A, is
traveling with speed V before it collides elastically with A.
Immediately after the collision, both objects move off at angles
(theta)>0 with respect to the original direction of B. Calculate
the value of the angle.
