31. The distance between two telephone poles is 50.0 m. When a 1.00-kg bird lands on the telephone wire mid- way between the poles, the wire sags 0.200 m. (a) Draw a free-body diagram of the bird. (b) How much tension does the bird produce in the wire? Ignore the weight of the wire. 32. A 3.00-kg object is moving in a plane, with its x and y W coordinates given by x 52-1 and y = 3 + 2, where x and y are in meters and is in seconds. Find the magnitude of the net force acting on this object at t=2.00 s.
