Justine is ice-skating at the Lloyd Center. What is her final velocity if she starts at 2.4 m/s and accelerates at a rate of 2.0 m/s/s for 3.5 seconds? Your answer should have 2 sig figs

12000j is work done

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
