## 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 vi hat bold = vii hat bold. As it passes through the region x = 0 to x = d, the electron experiences acceleration a = axi + ayj, where ax and ay are constants. For the case vi = 1.93 multiplied by 10^7 m/s, ax = 8.88 multiplied by 10^14 m/s2, and ay = 1.48 multiplied by 10^15 m/s2, determine the following, at x = d = 0.0100 m.

a)Find the position of the electron

b) the velocity of the electron

c) the speed of the electron

d)the direction of travel of the electron

## Homework Equations

For a, i tried using the equation Yf=1/2ayt^2

but the answer was wrong and I don't know if i used the wrong equation/numbers

b-d i don't know where to start

## The Attempt at a Solution

I used above equation and got -0.000235
