g A ball with a mass of 0.548 kg is dropped and has a velocity of 7.32 m/s just before hitting the floor. After impacting the floor, the ball bounces back up to a height of 1.34 m. Part A - If the duration of the impact is 2.26 ms long, what is the average force that the floor exerts on the ball

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (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.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
