A 362.9 kg gorilla is dropped on one end of a seesaw that is 3 meters long, elmer fudd, who weighs about 68 kg, is sitting on the other end.
a. What torque is provided by the gorilla landing on the seesaw?
b. What force does that provide to elmer fudd?
c. How high will Mr.fudd fly into the sky? (ignore air resistance).
