Mass 1 of 8 kg is initially moving at 10 m/s in the +x direction and it collides perfectly elastically with mass 2 of 3 kg initially at rest. What is the final velocity of mass 2 after the collision in m/s? (Note: the masses are not needed to answer this question.) _______
A proton (mass 1 u) moving at 9.00 10^(6) m/s collides elastically and head-on with a second particle moving in the opposite direction at 2.00 10^(6) m/s. After the collision, the proton is moving opposite to its initial direction at 5.40 10^(6) m/s. Find the mass and final velocity of the second particle. [Take the proton's initial velocity to be in the positive direction.]
