Mickey, a daredevil mouse of mass 0.0181 kg, is attempting to become the world? s first mouse cannonball. he is loaded into a spring-powered gun pointing up at some angle, and is shot into the air. the gun's spring has force constant of 59.5 n/m and is initially compressed a distance of 0.121 m from its relaxed position. if mickey has a constant horizontal speed of 2.01 m/s while he is flying through the air, how high above his initial location in the gun does mickey soar? take g = 9.81 m/s^2.

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
