Cart A is moving with a velocity of 18 m/s toward cart B, which is moving with a velocity of 9 m/s. Both carts have equal mass and are moving on a frictionless surface. The two carts have an inelastic collision and stick together after the collision. Calculate the velocity (in m/s) of the center of mass of the system before and after the collision.
