Two cars start from rest at the origin at t=0. The first has a known, constant acceleration k. The second has a weird engine that increases its power so that the car has an increasing acceleration given by at2, with α a known constant. When will the two cars again be at the same point? Where will they be when they are at the same point?

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?
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 block s speed be when it reaches x = 0? 8.79 m/s 5.86 m/s 4.14 m/s 2.90 m/s
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. What was its initial speed in this case? 18.98 m/s 12.47 m/s 8.82 m/s 14.90 m/s
