Please solve this problem for me: A large cruise ship of mass 7.00 107 kg has a speed of 10.0 m/s at some instant.
(a) What is the ship's kinetic energy at this time?
J
(b) How much work is required to stop it? (Include the sign of this value.)
J
(c) What is the magnitude of the constant force required to stop it as it undergoes a displacement of 2.00 km?
N
