2. A cart of mass 300 g moving along a straight track hits a 500 g cart which had been sitting still. After the carts hit, the 300 g cart has a speed of 1.0 m/s back to where it came from, while the 500 g cart is moving forward at 3.0 m/s in the same direction as the 300 g cart had been going at the beginning. How fast was the 300 g cart going before it hit the 500 g cart?
