part 3 OK, same sort of track, but now with d = 4.35 m. Now suppose the blocks starts on the track at x = 2.66 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? 4.00 m/s 4.83 m/s 5.30 m/s 5.65
PLEASE ANSWER PART 3
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 4.16 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -2.7 m. What will the blocks speed be when it reaches x = 0?

5.86 m/s |
Part 2 Same type of track as in the previous problem, this time with d = 3.07 m. The block starts at x = 0, and is given a push to the left with an initial speed of 2.76 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?

1.09 m |
