A speedboat is cruising at a speed of 11.6 m/s in still water when it shuts off its engines and coasts to rest. The water exerts drag forces on the speedboat such that its speed during coasting is given by v = vie−ct, where v is the speed at time t, vi is the initial speed at t = 0, and c is a constant. At a time of t = 21.0 s after the engines are cut, the speed is 5.00 m/s.
