The weight of a cart with a mass of 150 kg is ___ N. (Use 9.8 m/s2 for the acceleration due to gravity.)

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
