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.

2. Relevant 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)

= °

3. 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!
