Q1. For each graph of vx vs. t in the left column, choose the letter (a-i) corresponding to the appropriate description of motion. Not all descriptions will be used. Suppose the usual coordinate system (+x to the right, +y up, +z out of the page).
Q2. An electron moves in the positive x-direction a distance of 2.38 m in 2.95 x10-8 s, bounces off a moving proton, and then moves in the opposite direction a distance of 1.63m in 3.53x 10-8 s.
What is the magnitude of the average velocity of the electron over entire time interval?
