Two smooth spheres made of identical materical having masses m and 2m undergoes an oblique impact as shown in figure. The initial velocities of the masses are also shown. The impact force is along the line joining their centres. The coefficient of resistuation is 5/9. Calculate the velocities of the masses after the impact.

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.
