F= k(5C*7C)/5meters
Obviously I have to use Coulomb's law. I am not sure how to integrate the masses of each object into the equation. The answer will be in Newtons. Since they are both positive charges they will be accelerating away from each other.
Using Coulomb's Law, find the force between two objects that have charges of 5 Coulombs and 7 Coulombs, respectively. They are separated by a distance of 5 meters. For the same objects, one of which has a mass of 5kg and the other has a mass of 7kg, what is the force of gravity between them if...
Initial velocity= 13ms^-1
Final velocity= 0ms^-1
Time= 0.25s
A) Rate of acceleration = (V-U)/T = (0-13)/0.25 = -52ms^-2
B) Force exerted on the dumpster= F= (MV)/ T = (150*13)/0.25 = 7800N
I think?
A skateboarder with a mass of 150 kg is traveling at a final velocity of 13m/s and collides with a steel dumpster. The dumpster does not move. The skateboarder comes to a stop at 0.25 seconds. What is his rate of acceleration as he stops? How much force does he exert on the dumpster?
