A car and a truck start from rest at the same instant, with the car initially at some distance behind the truck. The truck has a constant acceleration of 2.10 m/s² and the car an acceleration of 3.40 m/s². The automobile overtakes the truck after the truck has moved 60.0 m.

The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with acceleration of -5.40 m/s2 for 4.15 s, making straight skid marks 63.3 m long, all the way to the tree. With what speed (in m/s) does the car then strike the tree? m/s

A hare and a tortoise compete in a race over a straight course 1.00 km long. Thetortoise crawls at a speed of 0.200 m/s toward the finish line. The hare runs at a speedof 8.00 m/s toward the Finish line for 0.800 km and then stops to tease the slowmoving tortoise as the tortoise eventually passes by. The hare waits for a while afterthe tortoise passes and then runs toward the finish line again at 8.00 m/s. Both thehare and the tortoise cross the finish line at the exact same instant. Assume bothanimals, when moving, move steadily at their respective speeds. (a) How far is thetortoise from the finish line when the hare resumes the racer (b) For how long in timewas the hare stationary?

A truck tractor pulls two trailers, one behind the other, at aconstant speed of 1.00x 102 km/h. It takes 0.600 s for the bigrig to completely pass onto a bridge 4.00 x 102 m long. Forwhat duration of time is all or part of the truck–trailer combinationon the bridge?
