Problem 23.29 (Multistep)
An accelerated electron
An electron is initially at rest. At time t1=0 it is accelerated
upward with an acceleration of a= 1 × 1019
m/s2 for a very short time (this large acceleration is
possible because the electron has a very small mass). We make
observations at location A, x= 16 meters from the electron
(see the figure).
