A block of mass 3.5 kg is initially at rest on a wedge of mass 20 kg, height 0.30 m, and an incline angle of θ =35° as shown in Figure P7.60. There is no friction between the wedge and the floor. Starting at the top of the incline, the block is released and slides toward the bottom of the wedge. At the same time, the wedge “recoils” and slides some distance L to the right. Find L when the block has reached the bottom of the wedge
