Two carts on a low friction air-track are connected by an unstretched spring. Cart 1 has an inertia of 1.5 kg while cart 2 has an inertia of 2.5 kg. The spring has a spring constant of 10 N/m and negligible inertia. You push cart 1 in the direction of the cart 2 with a constant force of 5.0 N. (a) What is the acceleration of the centre of mass of the cart-spring system? (b) What is the acceleration of each cart the instant you begin to push?
