A motorboat cuts its engine when its speed is 10.0 m/s and then coasts to rest. The equation describing the motion of the motorboat during this period is = ie-a , where is tin? speed .at time t, , is the initial speed at t = 0, and r is a constant. At t = 20.0 s. the speed is 5.00 m/s. (a) Find the constant c. (b) What is the speed at t - 40.0 s? (c) Differentiate die expression for (l) and thus show that the acceleration of the boat is proportional to the speed at any time.
