3. A helpful pig pushes a 20kg crate across the barn floor. Initially, the crate has a kinetic energy of E, = 30J. The pig applies a steady force of 7N on the box, and the kinetic frictional force of the floor on the box is 5N. Once the box has moved 3m to the right, what is the kinetic energy of the box?
