Hi, I have been given a lab in physics. I need to create a electromagnet. The power source is a D battery, and I am given 8 nails and 3 meters of wire. I was thinking the best way to construct it would be to cut the heads off the nails and make the most solid core I can. I do not have to use all...

Ok. Here is the moment of inertia equation for a, thin rectangular sheet, axis along one edge. (This is the door, hinge on one side) I = (1/3)(mass)(length)^2 Length is the Width that you are given in the equation. You should be able to get it from there.

I do have troubles with 2-d kinematics and modelling motion. In a vector that is a perfect square. You would model the vector to be, velocity as the x value, and g as the y value. Well we are on Earth so g will be 9.8. And velocity I have. I have no idea how to bring the angle into the equation...

Oh, so there has to be a remainder of 1, guess I forgot that. Sorry.

i^2 = -1 i^3 = -i i^4 = 1 i^5 = i 57 is divisible by 3. So, if I remember my calc class then it would be... -i (Don't be mad if I am completely wrong though, its just what I remember)

I apologize, I thought that would clear it up. Let me refraise the whole question. Tomarrow I do something our teacher likes to call 'Physics in the Real World.' For my presentation I decided to do a scene from the movie '2 Fast 2 Furious,' where one car ramps over another, both in mid air...

I have all the information, I just need to draw out the vectors, and see if there is more then a 1.27 clearance over the length of the cars. I just cannot figure out how to draw vectors anymore. The only variable you need to find is how high both the cars are during the ramping.

Ok, a simple vector problem. I found all the data, but have no idea to set it up. Here is what I am trying to do... I want to find it Car1 can ramp over the top of Car2, without hitting it. Both cars are ramping off the same ramp, and let's assume air resistance will not be significant...
