A cruise ship with a mass of 1.00×107 kg strikes a pier at a speed of 0.750 m/s. It comes to rest after traveling 6.00 m, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force exerted on the pier using the concept of impulse. (Hint: First calculate the time it took to bring the ship to rest, assuming a constant force.) V₁ = (0.750 m/s)î

A golf ball strikes a hard, smooth floor at an angle of 25.7 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.0523 kg, and its speed is 47.1 m/s just before and after striking the floor. What is the magnitude of the impulse applied to the golf ball by the floor? (Hint: Note that only the vertical component of the ball's momentum changes during impact with the floor, and ignore the weight of the ball.)
Shown in the figure is a single ball with mass, m, and initial speed, v, hitting the ground at an angle. The ball bounces off the ground and leaves with the same speed as it initially had and makes the same angle with the ground as shown in the figure.

A professional golfer is examining a video of a practice swing. The high‑speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only Δ?=0.671 ms, and the radar gun clocks the speed of the ball as ?b=131 mph after it comes off the club. The golf ball has a mass of ?b=45.9 g. What is the magnitude of the impulse imparted to the ball by the club? What is the magnitude of the average force of contact between the club and the ball?
