A Ball Hits a Wall Elastically Part A A ball of mass m moving with velocity strikes a vertical wall as shown in (Figure 1). The angle between the ball's initial velocity vector and the wall is 0, as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is Δ, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning...
