OK, same sort of track, but now with d = 4.93 m. Now suppose the
blocks starts on the track at x = 4.25 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?
5.90 m/s
8.48 m/s
6.00 m/s
5.79 m/s
Here we go again this time, d = 3.18 m. Suppose the block starts
on the track at x = 0. 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?
7.90 m/s
5.59 m/s
8.09 m/s
3.95 m/s
