A wedge mass m rest on horizontal surface. The inclination of the wedge is α. A ball of mass m moving horizontal with speed u hits the inclined face of the wedge inelastically and after hitting slides up the inclined face of the wedge. Find the velocity of the wedge just after collision. Neglect any friction.

A disk moving on a frictionless horizontal table collides elastically y with another identical disk as shown. The directions of motion of the two disks make angles 0 and ϕ with the initial line of motion as shown. Then Two identical balls A and B lie on a smooth horizontal surface which then takes up [...]

A smooth ball of mass m is suspended from a light string of length 1 m. Another ball of mass 2 m strikes the ball of mass in horizontally with a speed of u = root 35 m/s. The coefficient of restitution for the collision is e. The string becomes loose, when it makes an angle of 30∘ with the horizontal, find the value of e.
