Question

Use the diagram to answer the questions

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 2.29 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -1.71 m. What will the block s speed be when it reaches x = 0?

a.
5.01 m/s

b.
3.54 m/s

c.
1.06 m/s

d.
8.02 m/s
Same type of track as in the previous problem, this time with d = 3.60 m. The block starts at x = 0, and is given a push to the left with an initial speed of 2.23 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?

a.
-0.25 m

b.
-0.96 m

c.
0.96 m

d.
0.25 m
