Homework Statement
After year of over-eating and no exercise, Uncle Joe's is overweight, with a waist 50cm wide. He's also out of shape and can only hold his breath for 20 seconds. Worse, he can only jump 20cm high. But at his high-school reunion, he'd like to fool his old friends who haven;t seen him in years, into thinking otherwise by using special relativity. If he speeds by them on a vehicle that's traveling horizontally at (3/5)c, and he's standing vertically, holding his breath, and then jumping vertically, what will they observe for Uncle Joe's waist size (width), breath-holding time, and jumping height.
Homework Equations
L=L0 Sqrt(1-(v/c)^2)
The Attempt at a Solution
where v=3/5c c= 3.0*10^8 and L0= 50
I want to know if this is the right equation and if I am using it right
