Question

A 2170 kg car moving east at 10.5 m/s collides with a 3230 kg car moving east. The cars stick together and move east as a unit after the collision at a velocity of 6.00 m/s.
a) What is the velocity of the 3230 kg car before the collision?

2170*10.5E+3230V=(3230+2170)6E solve for V. Notice its direction has to be zero in N, or S direction.
