How much kinetic energy does a 50 kg object have if its moving at a velocity of 2 m/s? a) 25 joules b) 50 joules c) 100 joules d) 200 joules

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

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?

Ahorizontal force of 400.0 n is required to pull a 1760 n truck across the floor at a constant speed. find the coefficient of sliding friction.
