Question

a bullet is fired at and passes a piece of target paper suspended by a massless string. The bullet has a mass of m, a speed v before the collision with the target, and a speed (0.466)v after passing through the target. The collision is inelastic and during the collision, the amount of energy lost is equal to a fraction [(0.453)KEb BC] of the kinetic energy of the bullet before the collision. Determine the mass M of the target and the speed V of the target the instant after the collision in terms of mass m of the bullet and speed v of the bullet before the collision. Express answer t0 3 decimals.
