A running back (90kg) is running due south (270 degrees) down the field at a speed of 0.78 m/s when a linebacker (m=110 kg) hits him at a velocity of 0.34 m/s from an angle of 160 degrees (or toward 20 degrees south of east). If the collision is inelastic, what is the resulting velocity of the linebacker/ running back pair?
