Path of the ball before and after striking the wall.
Path of the ball before and after striking the wall.
A ball of mass \(m\) is moving with speed \(v\) toward a smooth vertical wall. The ball strikes the wall at an angle \(\theta\) relative to the normal to the wall and bounces off with the same speed \(v\) at the same angle \(\theta\), as shown in the figure. Which of the following vectors best represents the direction of the impulse exerted on the ball by the wall during the collision?
