The suspended 2:1 kg mass on the right is
moving up, the 1:7 kg mass slides down the
ramp (23 degree angle), and the suspended 8:7 kg mass on the
left is moving down. The coeficient of friction
between the block and the ramp is 0:14meu
The acceleration of gravity is 9:8 m/s2 : The
pulleys are massless and frictionless.

What is the acceleration of the three block
system?
ANSWER: acceleration is 5.52340
so how do tension?
What is the tension in the cord connected to the 2:1 kg block? What is the tension in the cord connected to the 8:7 kg block? Answer in units of N.
