Question
A toy battery-powered plane is hanging from the ceiling. With the motor turned off it is pulled to one side 0.20 m and released to swing as a pendulum. It takes 1 s to get to the far side of its swing. The plane now has the motor turned on and it flies in a circular path of radius 0.60 m. If the period of the circular motion is the same as the period of the simple harmonic motion, what is the approximate speed of the plane?
