A 84.7 kg refrigerator rests on the floor. How much work is required to move it at constant speed for 2.25 m along the floor against a friction force of 193.5 N

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
