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. The value of d is 2.10 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -2.58 m. What will the block s speed be when it reaches x = 0? 7.89 m/s 5.58 m/s 3.35 m/s 10.26 m/s
