6) Bob wants to measure the height of a cliff. Unfortunately, he only has with him a stopwatch and a
baseball. Luckily, he has a plan. While Jane stays at the bottom of the cliff, Bob climbs up the cliff
face. When he reaches the top, he throws the baseball as hard as he can, with a velocity of 33.7 m/s
at an angle of 22.5°. Some time later, Jane shouts that the ball landed 127 m from the bottom of the
cliff.
a) If Bob threw the ball from 1.50 m above the clifftop, how high is the cliff itself?

(10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P3.46. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees?
