An electron starts at rest. Gravity accelerates the electron in the negative y direction at 9.80 m/s2 while an electric field accelerates it in the positive x direction at 3.80×106 m/s2. Find its velocity 2.45 s after it starts to move.

  • physics - ,

    by the way, the answer is suposed to be in this form: ( , ) m/s. there are supposed to be two answers since there is acceleration in two dimensions.

  • physics - ,

    Velocity , in component form, is
    (Vx,Vy) = (at, -gt)
    At time t = 2.45 s,
    V = (9.30*10^6, -24.0) m/s
