Would anyone be able to give me a hint for this question? Do I take the integral? I have possible answers but I am unsure.
A rod of length 30.0 cm has a linear density given by:
D = 50.0g/m + 20.0xg/m^2
where x is the distance from one end measured in meters. a. What is the mass of...
Ok, thank you, I realize what I did wrong. I had it as hcos(theta)/[1+Uksin(theta)] which is upside down to what it's supposed to be: hsin(theta)/[1+Uksin(theta)] that's why it wasn't making any sense. :P . Thank you.
I don't know how to delete the other post. Sorry about that. Ok I know that because it's cot(theta) that is equal to cos(theta)/sin(theta). I've been trying to figure it out in reverse. So I multiplied the right side by Fg/Fg so that I got something that looks like: Fgcos(theta)h /...
A block slides down a curved frictionless track and then up an inclined plane. the coefficient of kinetic friction between the block and the incline is Uk. Use energy methods to show that the maximum height reached by the block is:
Ymax=
h
-----------------
1 + Uk cot(theta)
Prooving crazy formula
If anyone could help me with this that would be great. I keep getting stuck. Thanks.
