Question

# Hello, I have a certain question about this problem:

35. An electron is fired at 4.0 ×

10^{6} m/s horizontally between the parallel plates, as shown, starting at the negative plate. The electron deflects downwards and strikes the bottom plate. The magnitude of the electric field between the plates is 4.0 × 10^{2} N/C. The separation of the plates is 2.0 cm.

a. Find the acceleration of the electron between the plates.

b. Find the horizontal distance travelled by the electron when it hits the plate.

__c. Find the velocity of the electron as it strikes the plate.__

My Question is about c. would i solve for the velocity in the y direction? Because the x/horizontal direction is always conatant in speed throughout the motion. If you can help me understand, that would be great.
