A projectile (mass = 0.226 kg) is fired at and embeds itself in a target (mass = 2.04 kg). (the target is initially stationary). the target (with the projectile in it) flies off after being struck. what percentage of the projectile's incident kinetic energy does the target (with the projectile in it) carry off after being struck?

Mass of projectile, m = 0.226 kg Mass of target, M = 2.04 kg m = bullet mass M = target mass vf = (m / (m+M)) * 100% m = 0.226 M = 2.04 vf = (0.226 / (0.226+2.04)) * 100 vf = 9.97% Percentage of the projectile's incident kinetic energy does the target (with the projectile in it) carry off after being struck = 9.97%
