A particle leaves the origin with a speed of 2.4 times 106 m/s at 38 degrees to the positive x axis. It moves in a uniform electric field directed along positive y axis. Find Ey such that the particle will cross the x axis at x = 1.5 cm if the particle is an electron.

Forcey=-eE
displacement y=0=2.4E6 cos38-1/2 eT/mass*t^2 where e is absolute charge on electron, mass is mass of electron.
ok, what time does it cross the xaxis?
distancex=vx*t
.015/2.3E6 =t put that t in the displacement equation, solve for E.
