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

A car starts at t=0 with a velocity of 25 m/s. It drives with a constant velocity for 1 minute, then it accelerates with a constant acceleration of 0.5 m/s^2 for 20 seconds, then it continues with a new constant velocity for 1 minute. Draw a graph of the velocity versus time. Calculate the total distance the car travels.

The Batmobile, starting from rest, speeds up with an acceleration of magnitude 2.25 m/s2 through a distance of 225 m. It then applies the brake and slows down with an acceleration of magnitude 0.750 m/s2, until it finally stops after having traveled an additional distance of 675 m. Calculate the time that it takes to travel the entire 900 m from start to finish.

A remote controlled, battery operated toy car starts at t = 0 and travels 6.0 m at constant speed of 0.23 m/s. It now accelerates at 0.15m/s2 for another 6.0m and then maintains a constant speed for another 6.0m. The care now slows at 0.10m/s2 for 6.0m coming to a stop. How long did it take the car to travel the 24.0m?
