Two carts on a frictionless track before an inelastic collision.
Two carts on a frictionless track before an inelastic collision.
A cart of mass \(2.0 \text{ kg}\) moves to the right with a speed of \(6.0 \text{ m/s}\) on a horizontal frictionless track. It collides with a second cart of mass \(4.0 \text{ kg}\) that is initially at rest. The two carts stick together and move as a single unit. What is the speed of the center of mass of the two-cart system after the collision?
