Numerical Problems:
2 A man of 100 kg mass is standing on the surface of the earth of mass 6 x 1024 kg and
radius 6400km. Calculate the gravitational force between them.

their crystal patterns have been disrupted by stress

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
