8. OK, same sort of track, but now with d = 3.67 m. Now suppose the blocks starts on the track at x = 3.07 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? Please use the picture provided below to answer question 8 and 9. a. 3.64 m/s b. 4.33 m/s c.7.10 m/s d.5.02 m/s 9. 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? Please use the picture provided below to answer question 8 and 9. a.7.90 m/s b.5.59 m/s c.8.09 m/s d.3.95 m/s X
