18. a net force of 1.0n acts on a 4.0-kg object, initially at rest, for 4.0 seconds. what is the distance the object moves during the same time? be sure to show all work to support your answer.

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
