Aballistic pendulum is a device for measuring bullet speeds. one of the simplest versions consists of a block of wood hanging from two long cords. (two cords are used so that the bottom face of the block remains parallel to the floor as the block swings upward.) a 9.4-g bullet is fired into a ballistic pendulum in which the block has an inertia of 5.5 kg , and the block rises 60 mm above its initial position. part awhat is the speed of the bullet just before it hits the block? part bhow much energy is dissipated in the collision?

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
