Well I ran out of chances to get the right answer for T2.
I did f=ma and the answer was wrong. I swear...lol. Anyhow, I did it F = (2kg) (2.1 m/s2) and I tried F = (2kg) (9.8 - 2.1) thinking that M3 had the acceleration of gravity and the upward acceleration. (I don't know why I thought this...
T1 = 4.704 Ff + 2(9.8) + (1kg)(2kg)(2.1 m/s2) = 30.6 N right? - correct answer, thanks guys!
However! I calculated T2 the same way, and didnt get the right answer. I got 54.4 N and that is incorrect. Any ideas?
Wait. Okay, so somehow, I managed to get 1.9 something, but you're correct the answer is 2.1xxxx. I put it in and got it right.Now onto the tension. For the left rope, isn't it simply T1 = m1*g and T2 = m2*g?Galadirith, my professor said for the sake of life, that we are always to consider the...
Yeah I got that. But which mass do I use? The sum of M1,2,3? Or M1?
Ive tried a couple of different answers and none of them were right(though I don't have the right one).
Galadirith, the problem actually asks for what direction each mass is moving. I just filled it in here for simplicity...
Homework Statement
You have 3 masses. M1 = 4 kg. M2 = 1kg. M3 = 2kg, M1 is attached to M2 by a rope. M2 is attached to M3 by a rope. M1 is hanging from a pulley attached to the left end of a table, M2 is on the table, and M3 is hanging from a pulley attaced to the right end of the table.

Okay, I am done with workin on that section. I am onto a new question and I got all parts of the answer right so far, except the last part. The question is:
Consider two vectors by A = 5 i - 3 j and B = - i - 6 j.
(a) Calculate A + B
4i + -9j
(b) Calculate A - B
6i + 3j
(c) Calculate |A +...
Okay, so I redid everything. This is what I got.
PART A:
Magnitude: 31.95
Angle: sin x = 11 / 31.95 => 20.1*Part B:
Magnitude: 36.7
Angle: sin x = 9.5/36.7 => 15*
Wow I am sorry. Somehow I mistyped. F1 is on the X-axis(0*) and F2 is the other Tangent at the angle, not the other way around. That is how I got 24* (though I still think it is probably wrong).Thanks for the help guys, I am trying to get this as best I can.
side note, void, the question itself...
Greetings everyone! Thanks in advance for the help!
Homework Statement
Two parts to the problem. For both parts it asks for the magnitude of the net force and the direction of angle from the X axis.
Part A:
Two forces, F1 and F2, act on an object at rest at a 90* angle. F1 = 30N, F2 = 11N...
