I need to solve Q.1

I uploaded the answers I need to get but I need explanations on how to do it.

Here is a question with its answer. Could you please explain how to get each answer here?

Q1 distance from plate y 2.50E+00 E 4.00E+01 N/C delta t 5.008-01 us F 6.40E-18 N/C accel 7.03E+12 m/s2 delta y 8.78E-01 m final distance from plate .628+00 m b V X 3.00E+06 m/s delta x 1.50E+00 m v y final 3.518+06 m/s v mag 4.62E+06 m/sDuplicate 1. An electron is located 2.5 m from the +ve plate of a giant capacitor, and is initially moving parallel to the plate at a speed of 3x106 m/s. The electric field strength between the plates is 40 N/C. Determine, after a time interval of 0.5 us: a. The distance of the electron from the +ve plate b. The distance along the plate that the electron has moved. c. The electron's speed 2. An He+2 ion is placed between the plates of a capacitor at a distance of 2.0 mm from the negative plate. The separation between the plates is 4mm. Given that the inner surface of each plate has a surface area of 230 cm2 and a total charge of 0.3 uC, determine: a. How long until the ion strikes one of the plates? ( which one?) b. How fast will it be moving at this point? c. In what ways would your above answers change if the particle were an electron instead? d. Repeat parts a) and b) for the following case: The ion begins at the same distance from the negative plate, but is initially moving at a speed of 3x105 m/s parallel to the plates. e. How far would the ion have traveled along the axis of the plates in this time
