Problem
Cart A (mass 0.50 kg) moves toward stationary cart B (mass 0.75 kg) on a horizontal track. Cart B is attached to a wall by a light horizontal spring that exerts a horizontal force on cart B. Identify a choice of system for which linear momentum is conserved during the brief collision of the carts, and justify your choice.
