My solution doesnt match the Schaums Collgege Physics book.

AI Thread Summary
The discussion revolves around a physics problem involving two blocks and a pulley system, where the user is confused about the tension equation for block 2. The user derived the equation as Tension - f*m2*g = m2*a, while the Schaum's College Physics book states Tension = f*m2*g = m2*a. It is suggested that the book may contain a typo, indicating that the first equal sign should actually be a minus sign. This clarification resolves the user's confusion regarding the equations. The conversation highlights the importance of careful interpretation of physics problems and textbook accuracy.

Homework Statement



Imagine that a block of mass m2 is on top of block m1, which is on top a horizontal floor. m1>m2. A force F is applied to block 1 to the right. Both block1 and block2 are connected to the same pulley. In other words, one end of the pulley is connected to block1, and the other end of the pulley is connected to block2. The angle the cords make with each block is 0 degrees.For those of you with Schaum's College physics 10th edition, the question is chapter 3 excercise 35.



Homework Equations





The Attempt at a Solution



Let f be the coefficient of friction experienced by block2. In the free body diagram for block 2 (the block on top), I have developed the equation that Tension - f*m2*g =m2*a. But the book says that Tension = f*m2*g = m2*a. What have I done wrong?

I'd say you were correct.

I think it's just a typo. That first = sign was meant to be a minus sign.
 
Thanks Doc Al.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
