Consider two marbles where Marble 1 has a mass of m₁ = 160 g and Marble 2 has a mass of m₂ = 80 g. Peter rolls Marble 1 along the ground towards Marble 2. Marble 1 has an initial velocity of 1 = 3 m-s¹ to the right and Marble 2 is initially at rest. The collision between the marbles is perfectly elastic. After the collision both marbles are in motion.

determine velocity 1 and 2, the final velocities of each marble, immediately after the collision. Round both final velocities to the nearest integer.​
