I know this might sound simple to you but I was just wondering is the bumper car grid a series or parallel circuit? I need the answer for a project that I'm working on so that's why :smile:

Thanks a lot for the help. But I'm still stuck/confuse at some part hahaha...:biggrin: so is the tension times sine of the angle is the x component and tension (T) times the cosine of the angle is the y component? Also in part d, I know there are 2 type of acceleration there. One in the x...

A wall has a negative charge distribution producing a uniform horizontal electric field. A small plastic ball of mass 0.01kg, carrying a charge of -80.0uC is suspended by an uncharged, nonconducting thread of 0.30m long. The thread is attached to the wall and the ball hangs in equilibrium, as...

Thanks a lot for answering my question..I figure out all of them except for e. which is: The final speed of the object at displacemnt x=20 m So if I want to find the acceleration when x=20, I take: a= F/m and since F=0 then a= 0 too then I plug it into the last equation and solve for v...

I need help with this problem...please help me. I'm sorry the axis of the graph look a little weird...my scanner is not working so I have to make the graph myself T___T http://img395.imageshack.us/img395/8807/apphysics3cq.jpg A 0.20 kg object moves along a straight line. The net force acting...
