Astuntman wants to bungee jump from a hot air balloon 60.0 m above a the ground. he will use a uniform elastic cord, tied to a harness around his body, to stop his fall at a point 10.0 m above the ground. model his body as a particle and the cord as having negligible mass that obeys hooke's law. in a preliminary test, hanging at rest from a 5.00 m length of the cord, he finds that his body weight stretches it by 1.30 m. he will drop from rest at the point where the top end of a longer section of the cord is attached to the stationary balloon. hint: the spring constant changes with a longer piece of cord. a) what lenght of cord should he use? b) what maximum acceleration will he experience?

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
