A103 kg physics professor has fallen into the grand canyon. luckily, he managed to grab a branch and is now hanging 93 m below the rim. a student (majoring in lin- guistics and physics) decides to perform a rescue/experiment using a nearby horse. after lowering a rope to her fallen hero and attaching the other end to the horse, the student measures how long it takes for the horse to pull the fallen physicist to the rim of the grand canyon.
the acceleration of gravity is 9.8 m/s2 .
