A super rocket car traverses a straight track 2.30×105 m long in 1.00×10−3 s as measured by an observer next to the track. How much time delta t(clock) elapses on a clock in the rocket car during the run? delta t(clock) = ?s What is the distance L(driver) traveled in traversing the track as determined by the driver of the rocket car? L(driver) = ?m

Bob has just finished climbing a sheer cliff above a level beach and wants to figure out how high he climbed. All he has to use is a baseball, a stopwatch, and a friend on the ground below with a long measuring tape. Bob is a pitcher and knows that the fastest he can throw the ball is about ?0=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 ?1=0.910 st1=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 hit the ground ?=123 mx=123 m from the base of the cliff. How high above the beach was the ball when it was thrown?
