Homework Statement
The new earth-Pluto SuperShuttle line boast that it can take you between the two planets (which are about 5.0 h apart in distance) in 2.5 h according to your watch on board the shuttle. Assume that the shuttle travels at a constant velocity.
a.) What time interval must the synchronized space station clocks register between the shuttle’s departure and its arrival at Pluto if the advertisement is true?
b.) What is the shuttle’s cruising speed?
Homework Equations
∆Sab = √∆t^2ab - ∆x^2ab (?)
u=x/t (?)
The Attempt at a Solution
a) I believe the time interval would be coordinate time, as the space stations are in different locations, but are in the same inertial frame, although I'd appreciate a second opinion.
b) Stuck on this part mainly. Does cruising speed equate to velocity in this case? The formula ∆Sab = √∆t^2ab - ∆x^2ab won't work since t is less than x in this case, thus resulting in an imaginary number which can't be the answer.
Anyone have any advice? I'm not looking for the whole solution to be given to me, but I'm at a standstill in terms of my understanding of how the problem works...
