A physics student stands on a cliff overlooking a lake and decides to throw a golf ball to her friends in the water below. She throws the golf ball with a velocity of 19.5 m/s at an angle of 33.5 ∘ above the horizontal. When the golf ball leaves her hand, it is 14.5 m above the water. How far does the golf ball travel horizontally before it hits the water? Neglect any effects of air resistance when calculating the answer.

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.
