Academics

A speedboat starts from rest and accelerates at +2.01 m/s2 for 7.40 s. At the end of this time, the boat continues for an additional 5.90 s with an acceleration of +0.518 m/s2. Following this, the boat accelerates at -1.49 m/s2 for 8.05 s.

(a) What is the velocity of the boat at t = 21.35 s?

m/s

(b) Find out the total displacement of the boat.
