Sam is taking his girlfriend Sally out for a ride in his boat. He starts out at rest. He accelerates with an acceleration of 0.263 m/s^2 for 92.1 s. At that time Sally decides they are going fast enough and the boat moves at constant speed for a distance of 286 m. Then Sally decides she want to go a little faster and they accelerate at 0.197 m/s^2 for another 45.1s.
Total displacement of boat = 2690m
A)What is the final velocity of the boat?
B)What is the total time the boat moves?
