A 0.10 kg rubber ball strikes a smooth vertical wall with a speed of 5.0 m/s at an angle of 30° to the normal. It rebounds with the same speed and angle. Which of the following best describes the direction of the impulse delivered to the ball by the wall?
(a) Parallel to the wall, opposite to the component of the velocity along the wall
(b) Along the initial velocity vector of the ball
(c) Perpendicular to the wall, directed away from the wall
(d) Perpendicular to the wall, directed toward the wall
