The motor exerts a force of F on the cable to pull crate A of mass m along the incline plane. The coefficients of kinetic friction between the crate and the plane is Hk = 0.25. For m = 29 kg 023, FN (29) (9.81) cos (23) N. F = 25t2 N, where t is in seconds, if the crate starts to move at 3.20 seconds, determine the impulse resulted from the weight of the crate Wat 5 seconds.
