A 70 kg bicyclist is coasting down a long hill with a 1.9 degree slope. He's moving quite rapidly, so air drag is important. His cross-section area is 0.32 m^2 and his drag coefficient is 0.88. What speed does he eventually reach, in mph?

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?
