A particle of mass 2.20 ✕ 10−9 kg and charge 3.00 pC is movingin a vacuum chamber where the electric field has magnitude 1.50 ✕103 N/C and is directed straight upward. Neglecting other forcesexcept gravity, calculate the particle’s acceleration and velocityafter 2.00 s if it has an initial velocity of 3 m/s in the upwarddirection. (Assume the upward direction is positive. Indicate thedirection with the signs of your answers.) I know I need to usekinematics, but I keep getting incorrect answers. . . .
