A speedboat starts from rest at t = 0 s, and speeds up with a constant acceleration of 4.01 m/s2 for 6.00 s. Then it continues with a uniform speed for another 6.00 s. Finally, it slows down with a constant acceleration of −3.41 m/s2 . In your written work, include the velocity vs. time and acceleration vs. time graphs for this motion. The numerical values on the graphs are required.
(a) How long does it take for the speedboat to come to a full stop? Time is measured from the beginning at t = 0 s s
(b) What is the total displacement of the speedboat? m

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...

A speedboat starts from rest with a constant acceleration of +1.50 m/s2. After 4.00 seconds, its acceleration changes to +1.00 m/s2. After another 5.00 seconds, its acceleration changes to zero and the boat travels with constant velocity for a further 10.0 seconds. The boat then slows down and stops by accelerating at -2.00 m/s2. 1. Calculate the velocity and displacement of the boat at t = 4.00 seconds. 2. Calculate the velocity and displacement of the boat at t =...
