Questions
Ellywick decides tо try tо mоve through а forest by brаchiаtion, swinging below a handhold to move forward to the next handhold. Weighing a petite 40 kg, Ellywick has an arm length (hand to shoulder) of 0.60 m. We can model her motion as that of a point mass swinging at the end of a 0.60-m-long, massless rod. At the lowest point of her swing, Ellywick is moving at 2.9 m/s. What upward force must a branch provide to support the swinging Ellywick?
