The air exerts a forward force of 10 N on the propeller of a 0.20-kg model airplane. if the plane accelerates forward at 2.0 m/s², what is the magnitude of the resistive force exerted by the air on the airplane? A boat moves through the water with two forces acting on it. ne is a 2000 N forward push by the motor, and the other is an 1800-N resistive force due to the water. a) what is the acceleration of the 1000 kg boat? b) if it starts frpù rest, how far will it move in 10 s? c) what will its velocity be at the end of this time? Please help me solve these questions; I do not know what method to use. SOS!
