Neglecting air resistance, a 8 kg bowling ball released from rest from a building and falls for 45 m. What is the magnitude of the ball's velocity as it is about to hit the
sidewalk.

the answer is a. at the equator

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
