- That's what I thought too! But the answer choices it gave were 8 m/s, 4 m/s, 2 m/s, and 6 m/s so I'm confused. I went with 8 and it was wrong.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 ?0=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 ?1=0.510 s the ball is once again level with Bob. Bob cannot see well enough to the time when the ball hits the ground. Bob's friend then measures that the ball landed ?=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?The Statue of Liberty in New York City is approximately 305 ft305 ft tall.
