Engineering mechanics 13th edition Hibbler 13.7P

Question

If the 53-kg starts from rest and travels a distance of 5m up the plane in 6s, determine the magnitude of the force P acting on the crate. The coefficient of kinetic friction between the crate and the ground is 0.29.

Answer 1

Draw the free body diagram of the crate in incline plane.

Therefore, the magnitude of the force P is 546.62 N
