Question
A ball of mass 5kg, moving with a velocity of 4 m/s collides with another ball of mass 10kg, moving with a velocity of 1m/s in the opposite direction. If the two balls stick together after collision, calculate their common velocity.
Answers
conserve momentum
5(4) + 10(-1) = (5+10)v
solve for v
5(4) + 10(-1) = (5+10)v
solve for v
