A model airplane of mass 0.530 kg is flying at constant speed in a horizontal circle at one end of a 29.0 m cord and at a height of 11.0 m. The other end of the cord is tethered to the ground. The airplane circles 3.60 times per minute and has its wings horizontal so that the air is pushing vertically upward.

(a) What is the acceleration of the plane?

(b) What is the tension in the cord?

(c) What is the total upward force (lift) on the plane's wings?
