And all the information we were given is on the question so I'm assuming its not frictionless

m1 and m2 are atached by a string on a pulley so wouldn't their accelerations be the same?

Homework Statement Block 1 with mass m1=4.04 kg rests on a very low friction horizontal ledge. This block is attached to a string that passes over a pulley, and the other end of the string is attached to the hanging block 2 of mass m2=2.02 kg, as shown. The pulley is a uniform disk of radius...

haha yes

ok i tried again and got the right answer, just an algebra mistake. Thank you so much

5.3m/s^2 worked but how did you get that? Did you just solve for Tmp in terms of a and plug that into the other equation?

-18.99 m/s^2

So i solved for a=(F*R*r+F-M*g)/(M*r^2+I) and got the wrong answer which is probably a sign problem. If I made a positive clockwise torque and defined positive y to be up would the second tension force be negative in the first equation?

sorry i guess i forgot to include that, i am supposed to find the magnitude of acceleration at the mans waist or CM. And yes that picture is the right setup

yes, yes i am. Thank you I didn't really make that connection

the 2 different tension forces and the acceleration

Homework Statement A man is pulling himself up to a pulley that consists of two disks welded together as shown(same center). The man is currently pulling straight down on the rope in his hands with a force of magnitude 447.2 N (on the bigger disk). The other rope is also vertical and is...

Thanks for the reference, I found it with the equation w=sqrt(k/m)

Homework Statement An "ideal" spring with spring constant 0.45 N/m is attached to a block with mass 0.9 kg on one end and a vertical wall on the other. The floor has negligible friction, and you give the block a push and then let go. You observe that the block undergoes simple harmonic motion...
