My answer is 3.6 m/s. Am I right? The question is - A 20 kg cart moving at 10m/s bumps from behind an 80kg cart initially moving at 2m/s in the same direction. The two carts stick to each other after the collision. Calculate the speed of the carts after they collide.

Cart A has a mass of 1.00 kg and is moving rightward at 27.6 m/s prior to the collision with Cart B. Cart B has a mass of 0.50 kg and is moving leftward with a speed of 42.9 m/s. After the magnetic repulsion of the two carts, Cart A is moving leftward at 10.1 m/s. Determine the post-collision speed and direction of cart B.

8) In a lab demonstration, a cart with mass 0.15 kg that is moving at 0.6 m/s collides against a second cart that is at rest previously to the collision. The carts are padded with Velcro so they stick together, moving as a unit after the collision with speed 0.18 m/s. What is the mass of the second cart?
