A wedge of mass m and triangular cross- section (AB = BC = CA = 2R) is moving with a constant velocity `-v hat`I towards a sphere of radius R fixed on a smooth horizontal table as shown in figure. The wadge makes an elastic collision with the fixed sphere and returns along the same path without any rotaion. Neglect all friction and suppose that the wedge remains in contact with the sphere for a very shot time. `Deltat,` during which the sphere exerts a constant force F on the wedge.  eltat.`
