A box is released from rest at the top of a ramp at timet = 0. It slides down the ramp and collides with a spring. At time t = t4, the box first comes in contact with the spring. A short while later at time t = tg, the spring reaches its maximum compression. Then the spring recoils (starts getting longer again). At time t = t42, the spring returns to its natural length and it separates from the box again. The light gray depictions of the box in the figure below labeled A and B indicate how A www Mwww B far down the ramp the box would be at times ta and tg, respectively. At time t42, the box is back in location A. In the questions below, assume that you can ignore the mass of the spring. 1. As the block slides down the ramp, engages the spring, comes to a stop, and then gets pushed back up the ramp again, there are four forces acting on it: weight (w), normal force from the ramp (N), spring force (F,), and friction from the ramp (Ff). Your task is to fill in the table below. In each of the three time intervals (0 < t < ta, ta < t < tB, and te < t < ta2), indicate whether the individual forces produce positive (+), negative (-), or zero (0) work. 0
