Reference no: EM13238646

The model airplane in figure below is flying at a speed of 19 m/s on a horizontal circle of radius 17 m. The mass of the plane is 0.73kg. The person holding the guideline pulls it in until the radius becomes 12 m. The plane speeds up, and the tension in the guideline becomes four times greater. What is the net work done on the plane?
