Bob has just finished climbing a sheer cliff above a beach, and wants to figure out how high he climbed. all he has to use, however, is a baseball, a stopwatch, and a friend on the beach below with a long measuring tape. bob is a pitcher and he knows that the fastest he can throw the ball is about =34.1 m/s. v0=34.1 m/s. bob starts the stopwatch as he throws the ball (with no way to measure the ball's initial trajectory), and watches carefully. the ball rises and then falls, and after =0.510 st1=0.510 s the ball is once again level with bob. bob cannot see well enough to time when the ball hits the ground. bob's friend then measures that the ball landed =126 mx=126 m from the base of the cliff. how high up is bob, if the ball started exactly 2 m above the edge of the cliff?
