You pull a 70-kg crate at an angle of 30° above the horizontal. How hard do you have to pull to keep the crate moving with constant velocity if the ɱk = .4?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
