The distance between two telephone poles is 42.8 m. When a 1.00-kg bird lands on the telephone wire midway between the poles, the wire sags 0.220 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. N

A car with a mass of 1453 kg is rolling along a flat stretch of road and eventually comes to a stop due to rolling friction. If the car begins with a speed of 10.0 m/s and the car comes to a stop in 6.88 s, what is the coefficient of rolling friction between the tires and the road?

A block lies motionless on a horizontal tabletop. You apply a force Fapp horizontally to the block, but it does not move. What can you say about the relative sizes and magnitudes of Fapp, the static friction force between the block and the table, and the kinetic friction force between the block and the table?

(a) Why does an ordinary rifle recoil (kick backward) when fired? (b) The barrel of a recoilless rifle is open at both ends. Describe how Newton’s third law applies when one is fired. (c) Can you safely stand close behind one when it is fired?

The distance between two telephone poles is 60.0 m. When a 1.00-kg bird lands on the telephone wire midway between the poles, the wire sags 0.210 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. N
