A cruise ship with a mass of 1.43 x 107 kg strikes a pier at a speed of 0.712 m/s. It comes to rest 4.94 m later, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force (in N) exerted on the pier using the concept of impulse. (Hint: First calculate the time it took to bring the ship to rest. Assume the ship moves in the positive direction. Indicate the direction with the sign of...
A cruise ship with a mass of 1.33 ✕ 107 kg strikes a pier at a speed of 0.612 m/s. It comes to rest after traveling 4.94 m, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force (in N) 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. Indicate the direction with the sign of your answer.)
A cruise ship with a mass of 1.1 × 107 kg strikes a pier at a speed of 0.65 m/s. It comes to rest over a distance of 5.9 m, damaging the ship, the pier, and the tugboat captain’s finances. Assume a constant acceleration occurs during the collision. Find the average force Fsp being exerted on the pier as the ship hits it, in terms of the time of interaction Δt, the initial velocity of the ship v, and the...
1. Freddie and Carly decide to play a trick on Lewbert by suspending a mannequin that is made-up as a Zombie from a 3 m long, 0.35 mm diameter steel wire in the middle of the lobby. The Zombie has a mass of 17 kg. What is the change in length of the wire due to the weight of the Zombie? 2. Luna Loggerhead is riding on a playground merry-go-round at a radius of 1.8 m. If she must hold...
