The distance between two telephone poles is d = 48.0 m. When a 0.600-kg bird lands on the telephone wire midway between the poles, the wire sags h = 0.198 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. An object of mass m1 = 3.00 kg placed on a frictionless, horizontal table is connected to a string that passes over a pulley...

The distance between two telephone poles is
d = 49.0 m. When a 0.750 kg bird lands on the
telephone wire midway between the poles, the wire sags
h = 0.196 m. How much tension (in N) does the
bird produce in the wire? Ignore the weight of the
wire.

A light rope is attached to a block with mass 3.00 kg that rests on a frictionless, horizontal surface. The horizontal rope passes over a frictionless, massless pulley, and a block with mass m is suspended from the other end. When the blocks are released, the tension in the rope is 15.3 N . part a) Draw free-body diagram for the 3.00-kg block. Assume block is moving to the right. Draw the vectors starting at a black dot. The location...
