Arace car travel on a racetrack at 44m/s and slows down at a constant rate to a velocity of 22m/s over 11s. how far does it move during this time

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

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?
