Homework Help: Physics Help

Posted by Cat21 on Saturday, August 6, 2011 at 3:33pm.

A small, 200 g cart is moving at 1.50 m/s on an air track when it collides with a larger, 2.00 kg cart at rest. After the collision, the small cart recoils at 0.890 m/s.
Q: What is the speed of the large cart after the collision?

How do you set this up? Would it be like (mass of small cart)/(mass of large cart)*1.50m/s? but then how do you use the 0.890 m/s?
