A woman of massm=50.1kg sits on the left end of a seesaw-a plank of lengthL=3.99m-pivoted in the middle as shown in the figure.

(a)First compute the torques on the seesaw about an axis that passes through the pivot point. Where should a man of massM=68.6kg sit if the system (seesaw plus man and woman) is to be balanced?

(b) Find the normal force exerted by the pivot if the plank has a mass ofmpl=10.2kg.
