Blocks A, B, and C are placed as in the figure (Intro 1 figure) and connected by ropes of negligible mass. Both A and B weigh 23.2 N each, and the coefficient of kinetic friction between each block and the surface is 0.31. Block C descends with constant velocity.(adsbygoogle = window.adsbygoogle || []).push({});

Find the tension in the rope connecting blocks A and B.

What is the weight of block C?

If the rope connecting A and B were cut, what would be the acceleration of C?

[tex]\sum[/tex]F_{x}=T_{1}sin36.9-[tex]\mu[/tex]

[tex]\sum[/tex]F_{y}=T_{1}cos36.9-w

I tried to find the tension between A and B, but it turned out wrong. I think there is something wrong with the equation I used. =/

And I'm completely at a lost as to how you answer the other two questions.

Help is appreciated! Thanks! =)
