Speedboat starts from rest and accelerates

Reference no: EM13556529

A speedboat starts from rest and accelerates at+1.91 m/s² for 7.00 s. At the end of this time, the boat continues for an additional 6.00 s with an acceleration of+0.518 m/s². Following this, the boat acceleratesat -1.47 m/s2 for 8.00 s. What is the velocity of the boat at t = 21.0 s?
