The Stanford Linear Accelerator (SLAC) accelerates
electrons to c=0.99999997c in a 3.10 km-long
tube.
Part A
If they travel the length of the tube at full speed (they don't, because they are accelerating), how long is the tube in the electrons'
reference frame?

A large hot air balloon rising vertically is tracked by an observer located 4 miles from the lift-off point. At a certain moment, the angle theta between the observer's line of sight and the horizontal is pi/3, and it is changing at a rate of 0.1 rad/min. Let h be the height of the balloon at time t. Choose all of the following that is correct.
a. tan(theta) = h/4
b. at the moment when theta = pi/3, the balloon is rising at the rate 96 mph
c. tan(theta) = 4h
d. at the moment when theta = pi/3, the balloon is rising at the rate 0.8 mph
e. dh/dt = (4)/(cos(^2)*theta) * (d*theta/dt)
R3M.8 The new earth-Pluto shuttle shuttle line boasts that it can take you between the two planets (which are about 5.0 hours of distance apart) in 2.5 hours (according to a rider’s watch). Assume that acceleration and deceleration periods are very brief so that you spend essentially all the trip traveling at a constant velocity.
a) What time interval must synchronized clocks in the solar system’s reference frame register between the shuttle’s departure from earth and its arrival at Pluto if the advertisement is true?
b) What is the shuttle’s cruising speed?
