D(A)=D•√(1- β1²)=D•√(1- 0.54²)=0.842•D
D(B)=D•√(1- β2²)=D•√(1- 0.74²)=0.673•D
D(A)/D(B)= 0.842/0.673=1.25
Two spaceships A and B are exploring a new planet. Relative to this planet, spaceship A has a speed of 0.54c, and spaceship B has a speed of 0.74c. What is the ratio DA/DB of the values for the planet's diameter that each spaceship measures in a direction that is parallel to its motion?
I keep getting 1.37 which is the incorrect answer. I understand in general how to do the problem, but I must be missing a step
