You have been hired to design a family-friendly see-saw. Your design will feature a uniform board (mass M=8kgM=8 kg, length L=2.9mL=2.9 m) that can be moved so that the pivot is a distance dd from the center of the board. This will allow riders to achieve static equilibrium even if they are of different mass, as most people are. You have decided that each rider will be positioned so that his/her center of mass will be a distance xoffset=19cmxoffset=19 cm from the end of the board when seated. You have selected a child of mass m1=23kgm1=23 kg (on the right), and an adult of mass m2=63kgm2=63 kg (on the left) to test out your prototype.(A) Determine the distance dd in meters.(B) Determine the magnitude of the force exerted on the pivot point by the see-saw while in use in newtons.
