A 0.143 kg baseball, thrown with a speed of 44.6 m/s, is hit straight back at the pitcher with a speed of 53.0 m/s. (a) What is the magnitude of the impulse delivered by the bat to the baseball? Momentum is a vector. When the baseball changes direction, the direction of the momentum changes, too. Make sure you take this into account when you find the change in momentum. In other words, one of the momenta should be negative, and the other should be positive. kg · m/s (b) Find the magnitude of the average force exerted by the bat on the ball if the two are in contact for 1.92 x 10-3 s. S. kN

A 40.0-g bullet moving at a 250.0 m/s passes through a 2.40 cm thick sheet of foam plastic and emerges with a speed of 90.0 m/s. Assuming that the speed change takes place uniformly, calculate the average force that impeded the bullet's motion through the plastic. (Hint: You can apply the impulse-momentum theorem to solve the problem.)
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 6.00 m later, 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.)

Model rocket engines are rated by the impulse that they deliver when they fire. A particular engine is rated to deliver an impulse of 3.5 kg ⋅ m/s. The engine powers a 120 g rocket, including the mass of the engine. What is the final speed of the rocket once the engine has fired? (Ignore the change in mass as the engine fires and ignore the weight force during the short duration firing of the engine.)
