An 8kg ball traveling to the east at 10m/s collides, with a 2kg ball traveling to the west with a velocity of 5m/s. After the collision, they move together. Determine the final velocity of the balls.
Answered by R_scott
total momentum is conserved

(8 kg * 10 m/s)E + (2 kg * 5 m/s)W = 70 kg⋅m/s E

(70 kg⋅m/s) / (8 kg + 2 kg) = ? m/s
