You are pulling your younger sister along in a small wheeled cart. You weight 65.0 kg and the combined mass of your sister and the cart is 35.0 kg. You are pulling the cart via a short rope which you pull horizontally. You hold one end of the rope and your sister holds the other end. If you are accelerating at a rate of 0.10 m s-2, the rope is inelastic, and the frictional force acting upon the cart is 30 N:
1) What is the tension in the rope?
2) What forces are applying to the ground in order to produce this acceleration?
