Question

During a storm, a crate of crepe is sliding across a slick, oily parking lot through a displacement d=(-3.0m)i while a steady wind pushes against the crate with a force F=(2.0N)i+(-6.0N)j. (a) How much work does this force do on the crate during the displacement? (b) If the crate has a kinetic energy of 10J at the beginning of displacement d, what is its kinetic energy at the end of d?
