Q. A small, 100 g cart is moving at 1.20 m/s on an air track when it collides with a larger, 1.00 kg cart at rest. After the collision, the small cart recoils at 0.850 m/s. What is the speed of the large cart after the collision?
Q. A 345 g chunk of gold at 98.5 degrees Celsius is dropped into a 656 g of water at 22.5 degrees Celsius. What will the final temperature of the gold be after the system reaches equilibrium?
