Same type of track as in the previous problem, this time with d = 3.95 m. The block starts at x = 0, and is given a push to the left with an initial speed of 5.11 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down? -2.29 m 2 2.29 m 3 1.33 m 4 -1.33 m

Question

Hi, please can you help with the second question, I was able to do the first 

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 2.50 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -2.43 m. What will the block s speed be when it reaches x = 0? 1 6.81 m/s 2 4.82 m/s 3 3.86 m/s 4 9.53 m/s
