< Question 9 of 20 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 ground with a long measuring tape. Bob is a pitcher, and knows that the fastest he can throw the ball is to = 91.0 mph. 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 f₁ = 0.910 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 a distance of x = 332 ft from the base of the cliff. How high up is Bob if the ball started from exactly 5 ft above the edge of the cliff? height of the cliff: 5 fi TOOLS x10

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.

As the velocity of an inertial frame of reference increases with respect to a stationary observer, Einstcin's theory of special relativity predicts that the length of an object, measured in the dimension parallel to the motion of the reference frame, will A. decrease. B. remain unchanged. C. increase. D. increase at first but start to decrease when the speed of the reference frame equals half the speed of light. E. decrease at first but start to increase when the speed of the reference frame equals half the speed of light.
