A target rifle is held horizontally at rest and fired. The bullet with mass m_o leaves the barrel of the gun with speed v_o, linear momentum of magnitude p_o and kinetic energy KE_o. The gun has mass M_o (>>m_o).

The magnitude of the linear momentum of the recoiling rifle is ___ p_o.

The kinetic energy of the recoiling rifle is ___ KE_o.

The following information pertains to questions 5-9.

A red object with mass 3 m_o moves with a speed of 3 v_o toward the north. A blue object with mass 2 m_o moves with speed 6v_o toward the south. A perfectly inelastic collision occurs in which the two objects stick together and move as one object after the collision.

The magnitude of the sum of the linear momentum of the two objects just after the collision is ___ the magnitude of the sum of the linear momentum of the two objects just before the collision.

The magnitude of the total linear momentum of the two objects just before the collision is m_ov_o x ___.

If the speed of the red object had been slightly more, the magnitude of the total linear momentum of the two objects would have been ___.

Immediately after the collision, the two objects will ___.

The following information pertains to questions 10-12.

A bomb of mass 4 m_o initially at rest explodes into two pieces. One piece with a mass 3 m_o moves toward the east with speed v_o and kinetic energy KE_o.

The kinetic energy of the second bomb fragment is ___ KE_o.

A second bomb with more powder than the first one also initially at rest explodes into two pieces. The masses of these two pieces are the same as for the first bomb. The magnitude of the total linear momentum of the two bomb fragments for this second bomb is ___ the magnitude of the total linear momentum of the bomb fragments in the first explosion.
