Aprojectile of mass m1 moving with speed v1 in the +x direction strikes a stationary target of mass m2 head-on. the collision is elastic. use the momentum principle and the energy principle to determine the final velocities of the projectile and target, making no approximations concerning the masses. (use the following as necessary: m1, m2, and v1.)
