a 20 kg crate is initially moving down a wall at a speed of 2.0 m/s. Determine the magnitude of the average force exerted by the person in order to stop the crate's downward motion in a distance of .50 m. The person pushes in a direction 53 degrees above the horizontal, and the coefficient of friction between the crate and wall is .40. Can someone please help me??????
