Ok so both masses DO have acceleration? I guess I'll try writing Newton's law for each mass again; but in that case, I would HAVE to use the value of T that I got for the second mass into the first mass's equation wudnt I? or else I would have two unknowns: tension and acceleration ... Is the...

The thing is ... that's exactly what I did Doc. I don't know any kinematics but what you said b4, calculate the net force on that mass. That's what I did, here's the equation I used to calc. the net force (should be correct) -(10.1)(9.8)(sin38.3) + T (which you have to use the second block to...

Haha, should have made myself more clear. Of course I entered 9.0598 kJ on the web as an answer; was still wrong though (I'm only speaking I am terms of J to be more clear about what I did exactly). Umm well there's no way for me to scan this thing, but I cropped it off my homework online and...

Chi, I'm pretty sure that's the correct net work ... The net force I got is 552.429 N. What I was talking about is my net work which I multiplied that force by 16.4 (using the W = Fd formula) to get (which I then got 9059.83). What do I do with this net force? 9059 is not the correct answer so I...

Two blocks (with masses 10.1 kg and 65 kg) are connected by a string. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between the block and machine is 0.299. The acceleration of gravity is 9.8 m/s^2. Find the change in the kinetic energy of the block on...

Fermat, Thanks a million bud. You just made that problem look insanely easy after I worked on it for so long. I guess my mind just doesn't function the way yours does but I guess I just have to look more closely at the information I have. Thanks again, I got the answer. It's approximately...

Question on "Motion along a straight line" [edit: finally got the first one already so I erased it ...] Hey guys, I really appreciate this forum and all that are taking the time to help out. I wish to be part of this community and help out others in the future as well. I had a question on...
