Thanks Swapnil.

I've been working on a statics problem and I need to solve for theta, the equation I have right now is (4/5) = sin(theta) + cos(theta). I can't remember how to get theta out of this, my brain isn't functioning very well tonight... Been up too long :(

Anyone have any idea?

Ok well I figured it would be MORE THAN, but I entered that and it said I had already tried it before and it was incorrect. Then I tried LESS THAN and it said it was still incorrect. I thought this WAS the homework forums? Do you/anyone see any other possibilities for error?

I have some homework that is due on Wednesday (so I have some time to finish this), but I'm trying to get most of it done soon. I'm having trouble answering some Newton's laws questions and I don't understand why my answers are not correct. Here is what I have thus far: You push a box...

Hmm... I'm still not quite getting it. I need to factor the numerator then, correct? But it comes out as an imaginary number?

I'm having trouble figuring the oblique asymptote for this problem... I haven't ever done one of these before so I really don't know where to start. Here's the problem: y=(2x^2+5x+11)/(x+1)

So I have ball 'A' with mass 0.10 kg and velocity 1.4 m/s is traveling towards stationary ball 'C' with mass 0.10 kg. Ball 'C' is struck by ball 'A' and shoots off at an angle of 30 degrees to the x-axis, landing on the floor 1.20 meters below. I figured the time it takes the ball to hit the...

Thanks James, really appreciate it.

Alright so we did this stuff at the beginning of the year and haven't touched it until now and I can't remember exactly how it works... Say a ball is being spun in a vertical circular path and you need to draw a FBD for it at the highest point and lowest point on the circle. At the top you...

So here's the problem: I've already figured part a by setting potential energy (equalling charge multiplied by potential difference) equal to kinetic energy. My answer is 6.49*10^7 m/s. However, b is where I'm having trouble. I don't know how to go about it. Could someone please point me...

I'm having trouble starting this problem... I'm pretty sure I'll be able to figure it out if I can just get past the first question. I scanned the sheet because I'm lazy and I thought that you'd be able to understand the problem better that way anyways. So if someone could just point me in...

How can I find the rate at which heat is generated in the resister in an electric circuit connected to a 40-ohm resistor that is embedded in a .20 kg solid substance in a calorimeter. The external portion of the circuit is connected to a 60-volt power supply. I calculated the current and it is...

I see, so what I did was: So 4.68 X 10^11 electrons was very close to the correct answer. Did I do this right?

We just started this stuff in my AP Physics class and I'm not catching on to it too quickly... At least problem solving-wise. I thought I had all the concepts down, but maybe not. Here's a question I'm having problems with: How do I go about this one? I'm sure it's a pretty simple problem...
