You have been hired to design a family-friendly see-saw. Yourdesign will feature a uniform board (mass M =7 kg, length L = 11 m) that canbe moved so that the pivot is a distance d fromthe center of the board. This will allow riders to achieve staticequilibrium even if they are of different mass, as most people are.You have decided that each rider will be positioned so that his/hercenter of mass will be adistance xoffset = 23 cmfrom the end of the board when seated as shown.You have selected a child ofmass m = 21 kg (shown on the right),and an adult of mass n =4 times the mass ofthe child (shown on the left) to test out your prototype.
a) Determine the distance d inm.
b) Determine the magnitude of the force exerted on thepivot point by the see-saw in N.
