Homework Statement
As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x-axis in the xy plane with initial velocity v = vi. As it passes through the region x = 0 to x = d, the electron experiences acceleration a = ax + ay, where ax and ay are constants. For the case vi = 1.95 107 m/s, ax = 8.04 1014 m/s2, and ay = 1.52 1015 m/s2, determine the following, at x = d = 0.0100 m.
Homework Equations
(a) the position of the electron
yf = m
(b) the velocity of the electron
vf = m/s + m/s
(c) the speed of the electron
|vf| = m/s
(d) the direction of travel of the electron (i.e. the angle between its velocity and the x axis)
= °
The Attempt at a Solution
for this problem i used the kinematic equation and manipulated them and didnt get the right answers..i am a bio major, not a physics major, why do i have to learn this! please somebody help!
