A body is made in the form of wedge with an angle 45. See figure. A ball of mass m, moving horizontally at a speed v0 = m/s collides with the wedge of mass M=2m. As a result of the impact, the ball bounces vertically upwards. Neglect the friction between the wedge and horizontal surface. The speed of the ball just after the impact is |
