A speedboat starts from rest and accelerates at 201 ms2 for, Ask an Expert

Academics

A speedboat starts from rest and accelerates at +2.01 m/s² for 7.30 s. At the end of this time, the boat continues for an additional 6.10 s with an acceleration of +0.518 m/s². Following this, the boat accelerates at -1.49 m/s² for 8.45 s.

What is the velocity of the boat at t = 21.85 s? Find the total displacement of the boat.
