Abb gun is discharged at a cardboard box of mass m2 = 0.65 kg on a frictionless surface. the bb has a mass of m1 = 0.012 kg and flys at a velocity of v1 = 99 m/s. it is observed that the box is moving at a velocity of v2 = 0.39 m/s after the bb passes through it.1. write an expression for the magnitude of the bb's velocity as it exits the box vf.2. what is the bb's final velocity vf, in meters per second?
3. if the bb doesn't exit the box, what will the velocity of the box v'2, be in meters per second?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ν
=0.381meters and mass ν=3.1νν. initially ν"is on the ground and ν#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ν#just before it strikes the ground. assume the pulley bearing is frictionless.
