A wedge of mass `M` is kept at rest on smooth surface a particle of mass `m` hits the wedge normally. Find the velocity of wedge and particle just after collision. Take coefficient of restitution as `e`.

A smooth wedge of mass M is kept at rest on a smooth horizontal surface . Inclined face of the wedge make an angle theta with the horizontal . A particle of mass m collides normal to inclined face of wedge . If speed of the particle just before collision is u and coefficient of restitution is e then find velocity of wedge after collision .

A particle of mass m, collides with another stationary particle of mass M. If the particle m stops just after collision, then the coefficient of restitution for collision is equal to

A wedge of mass M and angle alpha rests on a smooth horizontal plane. A smooth sphere of mass m strickes it in a direction perpendicular to its inclined face and rebounds. If the coefficient of restitution is e, find the ratio of the speed of the sphere just before and just after the impact.

A wedge of mass M lies on a smooth fixed wedge of inclination theta . A particle of mass m lies on the wedge of mass M in the figure. All surfaces are frictionless and the distance of the block from the fixed wedge is l . Find. (a) Normal reaction between m and M (b) the time after which the particle will hit the fixed plane.
