A 0.31 kg cart (M) on a horizontal air track is attached to a string, which passes over a disk-shaped pulley of mass 0.080 kg and radius 0.012 m, and is pulled vertically downward with a constant force of 1.1 N. Find the acceleration of the cart and the tension in the string between the pulley and the cart. Include neat, labeled force diagrams, and all the steps of you derivations.
