Question

A marksman holds a rifle of mass M_R=3.00kg loosely inhis hands, so as to let it recoil freely when fired. He fires abullet of mass M_B=5.00g horizontally with a velocityrelative to the ground of V_BX = 300 m/s.

a.) What is the momentum of the system (rifle + bullet) before the man fires the bullet?

b.) What is the momentum of the system (rifle + bullet) after the man fires the bullet?

c.) Is the total momentum conserved?

d.) What is the recoil velocity of the rifle?

e.) What is the final momentum and kinetic energy of the bullet?

f.) What is the final momentum and kinetic energy of thebullet?

g.) What is the final kinetic energy of the bullet? Is it greateror smaller than that of the rifle?

h.) What is the final kinetic energy of the rifle?

i.) What is the total final kinetic energy of the system?
