- Homework Statement
- SLAC, the Stanford Linear Accelerator Collider, located at Stanford University in Palo Alto, California, accelerates electrons through a vacuum tube two miles long (it can be seen from an overpass of the Junipero Serra freeway that goes right over the accelerator). Electrons which are initially at rest are subjected to a continuous force of 1.1×10^-12 N along the entire length of two miles (one mile is 1.609 kilometers) and reach speeds very near the speed of light.
a) Calculate the final energy of the electron.
b) Calculate the final momentum of the electron.
c) Calculate the time required for the electron to go the two-mile distance.
- Relevant Equations
- E= F x d
E= .5mv^2, maybe?
I honestly just have no idea where to start on parts c and b. I tried 1.1*10^-12 N x 3218 m for part a, which was right. But I'm lost on b and c. I'm also wondering if we have to include a gamma factor in any of this, but I'm unsure how or where. Any help would be amazing.
