Figure 37-16 shows a ship (attached to reference frame S') passing us (standing in reference frame S ). A proton is fired at nearly the speed of light along the length of the ship, from the front to the rear. (a) Is the spatial separation ▵ x' between the point at which the proton is fired and the point at which it hits the ship’s rear wall a positive or negative quantity? (b) Is the temporal separation Δ t' between those events a positive or negative quantity? Figure 37-16 Question 2 and Problem 68.

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.
