Question

A bullet is fired at and passes through a piece of target paper suspended by a massless string. The bullet has a mass m, a speed v before the collision with the target, and a speed (.536)v after passing through the target. The collision is inelastic and during collision, the amount of energy lost is equal to a fraction [(0.273)KE b BC] of the kinetic energy of the bullet before the collision. Determine the mass M of the target and the speed V of the bullet before the collision. (please express answers to at least 3 decimals)

V = _______v

M = _______m

Explanation / Answer

post-collision bullet KE = (0.536)
