Physics

A woman of mass m = 58.9 kg sits on the left end of aseesaw—a plank of length L = 4.04 m, pivoted in themiddle.

(a) First compute the torques on the seesaw about an axis thatpasses through the pivot point. Where should a man of massM = 69.9 kg sit if the system (seesaw plus man and woman)is to be balanced?
1.702m (Correct)

(b) Find the normal force exerted by the pivot if the plank hasa mass of mpl = 12.8 kg.
1387.68N (Correct)

(c) Repeat part (a), but this time compute the torques about anaxis through the left end of the plank.
1.65m (Correct)

QUESTION: Suppose a 27.8-kg child sits 0.73 mto the left of center on the same seesaw as the problem you justsolved in the PRACTICE IT section. A second child sits at the endon the opposite side, and the system is balanced.

(a) Find the mass of the second child 10.05 kg?

(b) Find the normal force acting at the pivot point.____N?
