Solutions to various physics problems in a university-level physics course. Topics include calculating tension in wires, acceleration of objects connected by cables, and work done by forces. Problems involve calculating tension in a sagging telephone wire, acceleration of objects on a frictionless table, and work done by forces acting on an object.

The distance between two telephone poles is 50.0 m. When a 1.00-kg bird lands on the telephone wire midway between the poles, the wire sags 0.200 m. Draw a free-body diagram of the bird. How much tension does the bird produce in the wire? Ignore the weight of the wire. 2. An object with mass m1 = 5.00 kg, resting on a frictionless horizontal table, is connected to a cable that passes over a pulley and then is fastened to a hanging object with mass m2 = 10.0 kg, as in Figure shown. Find the acceleration of each object and the tension in the cable. What will be the tension if there is friction? (µk = 0.2)
