Hello tutors ! I need help with the following physics problem.

I need help with the following conceptual question.

Consider a parallel-plate capacitor with plate separation d, plate area A, whose plates have charge Q. A particle of charge q < 0 and mass m is released from rest at the negative plate of the capacitor and allowed to accelerate towards the positive plate. With what speed does the charge strike the positive plate? Answer in terms of d, A, Q, q, m, and/or ₀.
