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 if 1.53 x 10^7 kg strikes a pier at a speed of 0.652 m/s. It comes to rest 5.19 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 moces in the positive direction. Indicate the direction with the sign of...
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...
A large cruise ship of mass 6.20 ✕ 107 kg has a speed of 11.4 m/s at some instant. (a) What is the ship's kinetic energy at this time? J (b) How much work is required to stop it? (Give the work done on the ship. Include the sign of the value in your answer.) J (c) What is the magnitude of the constant force required to stop it as it undergoes a displacement of 2.70 km? N
A large cruise ship of mass 6.10 ✕ 107 kg has a speed of 10.4 m/s at some instant. (a) What is the ship's kinetic energy at this time? J (b) How much work is required to stop it? (Give the work done on the ship. Include the sign of the value in your answer.) J (c) What is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km? N
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...
