Can anyone help me with this Physics problem?

An electron has an initial velocity vector v 0 = (6.5 × 104 m/s) i hat. It enters a region where vector E = (2.0 i hat + 8.0 j hat) × 104 N/C.
(a) Determine the vector acceleration of the electron as a function of time.
(b)At what angle θ is it moving (relative to its initial direction) at t = 1.5 ns?(counterclockwise from its initial direction is positive)
