3. A 6 kg, 2 meter long, uniform teeter totter is situated as shown below. The
fulcrum is placed 30 cm to the left of the center of mass of the board. Calculate
the force, F, that the person at the end of the teeter totter must exert to place it in
rotational equilibrium. Note: when an object is not supported at its center of
mass, the weight of the object will cause torque
