## Question:

Starting from the position shown, assume that each horse moves to the right in such a way that the tension in the cord is the same in cases (a) and (b) and remains constant. Knowing that $\beta >\gamma$ and that in both cases (a) and (b) the horse advances by an equal amount L, determine which of the following statements is true: (1) the tension in the cord does more work in (a) than in (b); (2) the tension in the cord does exactly the same amount of work in (a) as in (b); (3) the tension in the cord does less work in (a) than in (b).
