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 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 crate of mass 9.6 kg is pulled up a rough incline with an initial speed of 1.58 m/s. The pulling force is 94 N parallel to the incline, which makes an angle of 20.2° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.02 m. (a) How much work is done by the gravitational force on the crate? 159.82 You have the correct magnitude of the work, but think carefully about the sign....
