A power-controlled model plane takes off with constant acceleration. If it requires a distance S = 4 m. and is moving at 6 m/s when it lifts off, (a) how much time does its takeoff require in sec.? An aeronautic engineer studying the mechanics of model plane shows that the acceleration of the model plane as tested is expressed as a = C + Dt where C and D are constants. Measurements obtained from videotape indicate that the second model plane requires 1.42 sec. and a distance of 4.3 m. to takeoff and is moving at 6.1 m/s when it lifts off. (b) Find the constant C. (c) Find the acceleration of the second model plane in m/s?.
