The suspended 2.3 kg mass on the right is
moving up, the 1.3 kg mass slides down the
ramp, and the suspended 7.7 kg mass on the
left is moving down. The coefficient of friction
between the block and the ramp is 0.15.
The acceleration of gravity is 9.8 m/s

. The
pulleys are massless and frictionless.
