linebacker and quarterback physics question?

A 110kg linebacker running at 2.0m/s and an 82kg quarterback running at 3.0m/s have a head-on collision in midair. The linebacker grabs and holds onto the quarterback.

Who ends up moving forward after they collide?

The quarterback or the linebacker

    Without going through detailed calculation, the quarterback has the larger momentum: 246 kg-m/s as compared to the linebacker's 220.0 kg-mg/s.

    Obviously, the quarterback ends moving forward after the collision, since he's got a larger momentum.

    Hope this helps.

    I'm not going to tell you the answer, but I will tell you a little bit about the physics behind it, specifically the law of conservation of momentum.

    Momentum =mass*velocity

    When two objects collide, no momentum is lost. With that understanding, we can equate the momentums into a formula:

    momentum1+momentum2= momentum3

    momentum three represents the two linebackers holding onto eachother. you know their total mass, so all you have to solve for is their velocity.
