Electron in Homogeneous Electric Field

[jakk2]

please help me :(

Electron inserted in a homogeneous electric field to measure 300 N / C, which
directed vertically upwards. The initial velocity of the electron is far
5,00 10^ × 6 m/s and goes to 30 degrees, above the skyline. a) Find the maximum height that
reaches the electron above the original level.

please help i m stuck

What is the force on the electron due to electric field?
What is the acceleration and its direction?
What are the vertical and horizontal components of velocity?
Which component remains constant and which component changes?
Which kinematic equation relates initial velocity, final velocity, displacement and acceleration?
