airboat with mass 3.5 x 102 kg including passengers has an engine that produces a net izontal force of 7.70 x 10² N, after accounting for forces of resistance. (a) Find for the eleration of the airboat (b)starting from rest, how long does it take the airboat to reach a ed of 12.0m/s? (c)after reaching this speed, the pilot turns off the engine and drifts to a stop ra distance of 50.0 m. Find the resistance force, assuming its constant. Suppose the pilot ting again from rest, opens the throttle partway. At a constant acceleration, the airboat then ers a distance of 60.0 m in 10.0 s. Find the net force acting on the boat.
