Question: Gibbons, small Asian apes, move by brachiation, swinging below a handhold to move forward to the next handhold. A 9.1kg gibbon has an arm length (hand to shoulder) of 0.60 m. We can model its motion as that of a point mass swinging at the end of a 0.60-m-long, mass less rod. At the lowest point of its swing, the gibbon is moving at 3.3m/s.
Part I: What upward force must a branch provide to support the swinging gibbon?
I need help to solve the above question and express your answer to two significant figures and include the appropriate units.
