A2-kg box is pushed by a force of 4 n for 2 seconds. it has an initial velocity vo = 2 m/s to the right. note: since this problem gives the time ∆t traveled, first look at momenta values and calculate the impulse using i = f ∆t = ∆p. after the momenta values are calculated, then calculate the kinetic energy and net work values.

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.
