1. A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. d is equal to 2.57 m. Suppose the block starts on the track at x = 0, at What minimum initial velocity (moving to the right) must the block have such that it will leave the track at x = 0 and go into freefall? 7.10 m/s 5.02 m/s 8.48 m/s 5.40 m/s
