On a very muddy football field, a 100kg linebacker tackles an 85kg halfback. Immediately before the collision, the linebacker is slipping with a velocity of 8.5 m/snorth and the halfback is sliding with a velocity of 7.3m/s east.

a) What is the magnitude of the velocity at which the two players move together immediately after the collision?

b) What is the direction of this velocity?
