A vertical spring with k = 6900 N/m is compressed 0.060 m. A 0.13 kg ball is placed on top of the spring and released, launching it into the air. How far above the launching point—corresponding to the spring’s free length—is the ball when it has a speed of 2.0 m/s? (Neglect air friction.) Group of answer choices

1.2 m

160 m

19 m

9.5 m

94 m

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?

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.
