Amotorboat cuts its engine when its speed is 8.2 m/s and coasts to rest. the equation describing the motion of the motorboat during this period is 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 t = 18.4 s, the speed is 5.00 m/s.
(a) find the constant c (in s-1)
(b) what is the speed at t = 40.0 s? (in m/s)
