A projectile (mass = 0.235 kilogram) is fired at and embeds itself in a target (mass = 1.26 kilogram). (The target is initially stationary).The target (with the projectile in it) flies off after being struck. Obtain what percentage of the projectile's incident kinetic energy does the target (with the projectile in it) carry off after being struck?
The distance between two telephone poles is 44.5 m. When a 1.00-kg bird lands on the telephone wire midway between the poles, How much tension does the bird produce in the wire
A 1000-kg car is moving at 30.0 m/s around a horizontal curve whose radius is 100 m. What is the magnitude of the frictional force required to keep the car from sliding
A cylinder contains 3.5 {\rm L} of oxygen at350 {\rm K} and 2.4 {\rm atm}. The gas is heated, causing a piston in the cylinder to move outward. The heating reasons the temperature to rise to 610 {\rm K} and the volume of the cylinder to increase to 9..
