Amodel airplane of mass 0.6 kg is attached to a horizontal string and flies in a horizontal circle of radius 6 m, making 1.6 revolutions every 5 s. (the weight of the plane is balanced by the upward “lift” force of the air on the wings of the plane.) the accelaration due to the gravity is 9.81 m/s2 . find the speed of the plane. answer in units of m/s.
