Some chipmunks are running back and forth along a tree branch. One chipmunk is at rest at t = 0 s and starts running to the right. It speeds up to a speed of 1.5 m/s in 3 s. How far does it run in this time? Another chipmunk starts from rest and runs to the left. It speeds up to a speed of 2.1 m/s in 3.2 s. It then slows to a stop in...
