Gibbons, small Asian apes, move by brachiation, swinging below a handhold to move forward to the next handhold. A \(9.0 \mathrm{~kg}\) gibbon has an arm length (hand to shoulder) of \(0.60 \mathrm{~m}\). We can model its motion as that of a point mass swinging at the end of a \(0.60-\mathrm{m}\)-long, massless rod. At the lowest point of its swing, the gibbon is moving at \(3.5 \mathrm{~m} / \mathrm{s}\). What upward force must a branch provide to support the swinging gibbon?
