Question
Static Equilibrium David and his sister Jessica are playing on a tree swing. David sits
on the swing while Jessica pushes him horizontally through an angle of 28.5 degree and
holds him there (Figure 3). If David weighs 80.5 pounds, find the magnitude of the
tension in the rope and the magnitude of the force Jessica must push with to keep
David in static equilibrium.
