Physics QUESTION PLEASE HELP!!!?

A uniform field E=-170000 j N/C exists between two plates of length L= 5 cm. A proton is fired at an angle of degrees 25 degrees CCW from the x axis with an initial speed of 5800000 m/s. Ignore gravity. a) Find its vertical coordinates as it emerges from the plate, assuming the proton will not hit any plate in... show more A uniform field E=-170000 j N/C exists between two plates of length L= 5 cm. A proton is fired at an angle of degrees 25 degrees CCW from the x axis with an initial speed of 5800000 m/s. Ignore gravity.

a) Find its vertical coordinates as it emerges from the plate, assuming the proton will not hit any plate in the process.

b) Find the angle at which it emerges from the x-axis.
