A 80.4-kg halfback moving south with a speed of 4.91 m/s is hit by a 96.9-kg opponent moving north with a speed of 2.89 m/s. If the collision is perfectly inelastic (meaning that the two players "stick" to one another), calculate the speed (in m/s) of the 80.4-kg halfback just after the hit.

Ireally need this answer sombody fast fast
