    Electric Potential Energy help

    I've just now received an email from my professor that this problem was canceled due to computer grading error. I believe what I did as correct though. Thanks for all the help :)

    Electric Potential Energy help

    I did all I can, and I'm stressed out over this. Thus, here I am. :( Here's the question (I substitute the numbers with alphabet letters): >Two point charges of magnitude of A nC and -B nC are separated by D m distance. >The acceleration of gravity is 9.8 m/s^2. The Coulomb constant, k, is...

    Calculating Forces & Friction to Stop a Car

    Well, to my current knowledge, the frictional force requires the mass of the car to be calculated: frictional force = coefficient of friction * mass Sorry if I'm not getting anywhere by your input.. I'm really trying here :(

    Calculating Terminal Velocity of Wooden Sphere

    Given: wooden sphere gravity = 9.8 m/s^2 radius of sphere = .18 m density of sphere = 801 kg/m^3 Drag coefficient = 0.5 I found out the velocity of the wooden ball to be 3.07 m/s (please confirm). Now it has to go through the air that has density of 1.2 kg/m^3. What would be the speed...

    Calculating Forces & Friction to Stop a Car

    Maybe I'm thinking way too deep for this problem, but here goes: -A car is traveling 11.7 m/s on a flat road. -Acceleration of gravity = 9.8 m/s^2 -The coefficient of friction between the road and the tires is 0.156 -What is the minimum distance in which the car will stop? I tried to...
