Homework Statement From point A, the marble rests at the height of 0.895 m. Then, it is released up to point B which has a height of 0.665 m. From point B to point C, the marble falls in a projectile motion. Calculate the Kinetic Energy on position B and the work done by friction from...

when i multiply the angular acceleration by the radius of the pulley, my units are m^2/s^2 which for me, looks the wrong unit for acceleration. where did i get wrong?

btw, is that a you give in your reply the linear acceleration or the angular?? because if that's linear, then that will be my answer in a.) right? and also, is my formula for t1 and t2 correct? t1=m1g-m1a and t2=m2a+m2g

gee, thanks a lot...maybe i will show you my solutions tomorrow...

will you help me using the torque method then? because what the instructor taught us was just up to moment of inertia.

so you're saying that i must use Newtonian approach to solve this problem? well, I've thought of that at first. But then again, there's this moment of inertia of the pulley, and it's stated there that the pulley is a homogeneous disk. Am i really going to ignore that moment-of-inertia thing...

rotational motion and moment of inertia---HELP! Homework Statement Two masses m1=2.00 kg and m2=1.00 kg are linked by a thread and thrown over a pulley whose mass is 1.00 kg. The radius of the pulley is 0.200 m. a) Find the acceleration a with which the weights move b) the tensions T1...
