A 130-kg crate is initially at rest on a horizontal frictionless surface. An applied force of 400 N to the right is exerted on the crate, causing it to move and cover a distance of 26.0 m. At the end of its path, the crate is found to be moving at a speed of 15.0 m/s. (a) What is the work done by the following forces: (i) weight of the crate, (ii) normal force exerted on the crate by the surface, (iii) applied force. (b) What is the net work done on the crate? (c) What is the change in its kinetic energy?
