Last time now, with d = 2.11 m. You start the block on the track at rest, somewhere to the left of x = 0. You then release the block from rest and let it slide down. What is the maximum value of x (that is, what is the closest to the origin) from which you can release the block from rest and have it leave the track at x = 0 and go into freefall?-1.32 m-1.06 m-0.75 m-1.45 m

- 13. A block slides along a track with an initial velocity vo = 7.0 m/s from one level to a higher level after passing through an intermediate valley. The difference h from the initial position to the elevated track is 0.89 m. The track is frictionless until reaches the top. What is the velocity of the block when it reaches the top of the track?6. Two blocks are connected by a light string passing over a light, frictionless pulley as shown in the figure. Block m1, initially at rest, is released from height h above the table. Block m,, which is the heavier block, begins to fall, while block m2 rises. a) Calculate the speed of m2 just as m¡ hits the table. b) Suppose block m, continues to rise without obstruction even after block m, hits the table. Calculate the maximum height above the table to which m2 rises. h▼ Part A A 56 g ice cube can slide without friction up and down a 30° slope.

- pervious question: Same type of track as in the previous problem, this time with d = 4.73 m. The block starts at x = 0, and is given a push to the left with an initial speed of 7.57 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? New question: OK, same sort of track, but now with d = 2.12 m. Now suppose the blocks starts on the track at x = 4.10 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.
