Find the total displacement of the boat

Reference no: EM13556798

A speedboat starts from rest and accelerates at +2.15m/s² for 8.35 s. At the end of this time, the boatcontinues for an additional 8.62 s with an acceleration of +0.629m/s². Following this, the boat accelerates at -0.968m/s2 for 8.87 s. (a) What is thevelocity of the boat at t = 25.84 s? (b) Find the total displacement of the boat.
