please help!

A ball is thrown upwards with speed v0. The ball has net charge Q and travels in the presence of an electric field whose potential function is v = (k/2) y2. Positive y is taken as vertically up. Do not neglect gravity.

a.)    Compute the electric field components.
b.)    Compute the net force on the ball.
c.)    How high does the ball go?

        Hint:    Use energy conservation.
        Note:    Assume y0 = 0 and vy (0) = v0y.
