An airboat with mass 4.36 102 kg, including the passenger, has an engine that produces a net horizontal force of 8.24 102 N, after accounting for forces of resistance.
(a) Find the acceleration of the airboat.
(b) Starting from rest, how long does it take the airboat to reach a speed of 15.5 m/s?
(c) After reaching that speed, the pilot turns off the engine and drifts to a stop over a distance of 50.0 meters. Find the resistance force, assuming it's constant.
