Forget it, my peers figured out the equations necessary for the problems I could not answer while I was at work. Thanks anyway.

I know the equation, but I don't understand where you are going with it.

Maybe someone can help me with a more difficult problem if no one is going to answer anything from above. A student performs a ballistic pendulum experiment using an apparatus similar to that shown in the figure. Initially the bullet is fired at the block while the block is at rest (at its...

Please help, I am really lost.

Homework Statement Tarzan swings on a 34 m long vine initially inclined at an angle of 41 degrees with the vertical. The acceleration of gravity is 9.81 m/s^2. What is his speed at the bottom of the swing if he starts from rest? What is his speed if he pushes off with a speed of 4 m/s...

Alright, thanks. I already knew that stuff. The question was killed anyway, so I don't have to do it. Thanks for your help.

Hey, I'm really having problems with this question and I don't really know what to do. I'm hoping someone can help me. Thanks in advance. Homework Statement A highway curves to the left with radius of curvature R = 35 m. The highway's surface is banked at 19 degrees so that the...

Alright, I figured it out using two formulas I found online. Thanks for your help.

W = mg W = 8(9.8) W = 78.4 I did F perpendicular as 78.4cos22 and found that to be 72.6912. I then did 78.4sin22 and found that to be 29.3692.

72.59N in the Y and 29.3692N in the X ?

Weight? The block has a mass of 8kg. It doesn't say any other forces.

a = .3806228374 m/s^2 There are no other forces acting on it.

If someone can help, that would be really nice. I need the answer to this question sometime before 12:00 tonight (it's 8:00 now) to get credit for it.

There is another problem that I don't really understand. An 8kg block is released from rest on an inclined plane and moves 2.2m during the next 3.4s. The acceleration of gravity is 9.8m/s^2. What is the coefficient of kinetic friction for the incline?

Hooray. I was going to try that days ago to see if that could be right, but didn't want to bother wasting one of my guesses on something that probably wouldn't be right. Thanks for your help. I'll probably need some more help tomorrow. Haha.
