What is the velocity of the tackle before the collision

Reference no: EM13281190

A running back with a mass of 82 kg and a velocity of 9 m/s (toward the right) collides with, and is held by, a 123-kg defensive tackle going in the opposite direction (toward the left). What is the velocity of the tackle before the collision for their velocity afterward to be zero? (Remember, velocity is a vector)
