I'm still lost... can you please explain what i have to do?! Can you give me an example of an answer at least?

Lol, thanks again :P Btw, where do you get the signs from? So that you won't have to give them to me every time... Soo; A) 18*6/2π+115 = 117.86 rpm? But it sais magnitude and direction... do i actually have to give a direction? B) r*117.86= 117.86 revolutions = tangential velocity? C)...

Homework Statement A wheel 1m in diameter is rotating on a horizontal plane in the clockwise direction with an angular speed of 115 rpm. It's angular acceleration is 18 rad/s2 A) What is the angular velocity (magnitude and direction) after 6 seconds B) What is the tangential velocity of a...

It can't be... It was on the test and many people got it right

But it was a question on the test lol... Here, i took a picture of the question in case i missed something. Thx!

But i don't have µ, I only have numbers that i gave in my first post...

Yeah, i didn't mean *15°, i was just saying that it's the force at 15°. Sry :P But i don't have the value of friction... How can i solve it?

Lol, Thanks ;) Umm, as i mentioned, there is a force pulling on block b at 15° above horizontal, and if the system is moving at constant velocity, (a=0) the opposite forces have to be equal. Therefore left (in my case, friction+Wx of block A) = Right (pull at 15° on block B). If I am right...

Homework Statement Block B on a frictionless table top (1.5kg) is connected by a cord to block A (3.8kg) with friction on an incline of 40degrees above the horizontal. Block B is being pulled at and angle 15degrees above the horizontal Block A is moving up the incline at constant...
