Document Summary

The crane lifts a bin of mass m with an initial acceleration a. Determine the force in each of the supporting cables due to this motion. P = 400 n and the coefficient of kinetic friction between. If mk = 0. 25 the 50-kg crate and the inclined plane is determine the velocity of the crate after it travels 6 m up the plane. Free-body diagram: here, the kinetic friction is required to be directed down the plane to oppose the motion of the crate which is assumed to be directed up the plane. The acceleration a of the crate is also assumed to be directed up the plane, fig. a. N + 400 sin 30 - 50(9. 81) cos 30 = 50(0) 400 cos 30 - 50(9. 81) sin 30 - 0. 25(224. 79) = 50a a = 0. 8993 m>s2. Kinematics: since the acceleration a of the crate is constant, v2 = v0.
