A baseball player hits a line drive horizontally from a height of 1 m. How long will it take the ball to hit the ground?

If the ball traveled 24 m horizontally while it was in the air, what was its initial

velocity?

What was its final velocity?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
