e^t or something of the sort.
Good! I would of also accepted "x".
YOU CAN'T STOP ME EVEN WITH YOUR TITLES MWAHAHAHAHA Jk this'll be the last oneHere's a bit of a harder one.
(The units for this expression are in natural units, this means the speed of light is given as "1")
Say we had a spaceship zooming through space, at t = 0 the spaceships coordinates is given as (0, 0). A star, located at coordinates (0, 10) explodes at t = 0, the light from the stars explosion moves in every direction with a speed of 1. The spaceships velocity is given as (0.5, 0) (IE: Moving at half the speed of light in the positive x-direction).
How far does the spacecraft move from the origin (0, 0) when the light from the exploding star hits it?
