Find the magnitude of the force required to accelerate an electron of mass 5.30 x 10 -3 kg from rest to a speed of 0.8 x 1010 m/s for a distance of 2.50 cm?

The wording of the problem is slightly dicey. I think it should be in a distance and not for , else some data is missing.
Assuming it is in, use v^2 = 0^2 + 2 a s to get tha accln a and then
F = ma
