The crate moves up the incline a distance d = 5 ft due to the action of the constant force P= 100 lb. The weight of the crate is W = 70 lb and the spring with constant k = 10 lb/ft is unstretched before the crate starts moving. Friction between the crate and the incline is negligible and the angle between the force P and the surface on which the crate slides is Beta = 30°. Letting Theta= 30°, determine the total work done by all forces after the crate has moved the distance d.
