A book with a mass of 1.5 kg rests on the edge of a desk 0.75 m above the floor. Given that the acceleration due to gravity is 9.8 m/s2, what is the book's
potential energy?

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
