A cart with a mass of 1 kg is moving at 2 m/s. It collides with a stationary cart of mass 3 kg. After the collision, both carts stick together. The images below show the situation before and after the collision. +2 m/s 1 kg 3 kg Before 1 kg 3 kg After What is the speed of the stuck together carts after the collision? 0.5 m/s 1 m/s 2 m/s 4 m/s
