Q. A cubic box of side a = 0.250 m is placed so that its edges are parallel to the coordinate axes. There is NO net electric charge inside the box, but the space in and around the box is filled with a nonuniform electric field of the following form: E(x,y,z) = Kz j + Ky k, where K = 3.70 N/(Cm) is a constant. What is the electric flux through the top face of the box?

Q. In soccer, a speed record was set for kicking a soccer ball at 43 m/s. If the soccer player kicked the ball from ground level at an angle of 30.0° from the horizontal, what would be the flight time of the soccer ball? Assume that air resistance is negligible.
