A model airplane weighing 640 g is attached to a rope of length 1.7 m and allowed to fly at a constant height 1.2 m above the ground where the rope is attached to a rock. The propeller puts out a constant force 2.1 N. At time t = 0 s, the plane moves counterclockwise (looking down at it) at a speed 1.5 m/s. (a) Write the position of the plane in relative coordinates at t= o. + (b) Write the initial velocity of the plane. (c) What is the initial acceleration of the plane?
