5) A seesaw is pivoted in the middle of a plank of length L = 3.90 m. Balloon 1 with lift F, = 1.60 N is tied to the left

a distance of x, = 1.35 m from the pivot.Balloon 2 with lift F2 = 2.70 N is tied on the right side a distance of x2 from the pivot. The seesaw has sufficient mass to keep the whole thing from flying away. a) At what distance from the pivot must balloon 2 be tied to balance these saw? (4 points) b) What would the lift of the balloon on the right have to be to balance the seesaw if the balloon were tied 1.38 m to the right of the pivot? (4 points)
