As your friend speeds past you you measure her rocket to be 8.4 m long but when her rocket was parked In your back yard it was 6.5 m long. How fast is she going? Please express your answer as a fraction of the speed of light; for example if her speed is 1.5x10^8 m/s = .5 c, your answer would be .5

Question

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
