A2000kg suv accelerates from rest at a rate of 3.00m/s^2. the total amount of force resisting its motion 1500n. how much force is applied to the suvs tires by the ground to make it accelerate? the suv now drives at a constant 18.0m/s. the total amount of force resisting it's motion is 2500 n. now how much force is applied to the suv's tires by the ground?

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?
