An airboat with mass 450 kg, including the passenger, has an engine that produces a net horizontal force of 970 N, after accounting for forces of resistance (see Fig. 4.7). (a) Find the acceleration of the airboat. (b) Starting from rest, how long does it take the airboat to reach a speed of 15.0 m/s? (c) After reaching that speed, the pilot turns off the engine and drifts to a stop over a distance of 80.0 m. Find the resistance force, assuming it's constant.
