Question
Two cars collide as shown
in the figure. The yellow car is initially heading
east and has a mass of 1000 kg. The red truck is
initially heading north and has a mass of 2000
kg. The two vehicles collide, stick together, and
veer off at a velocity of 16 m/s at a direction of
24 degrees east of north. You can ignore friction.
What is the speed of each car before the
collision?

momenum applies
1000*VyEast+2000VrNorth=(3000)16 *(cos24 East + sin24 Nirth)
Set the East components equal,and the N components equal, and solve for Vyellow and Vred

I am not about to get Vyellow or Vred by itself to solve
