A skier is coasting at 4.0 m/s. She reaches the crest of a hill and she accelerates downhill at a rate of 0.20 m/s^2 for 10 s. How far does she travel down the hill during the 10 s?

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.
