The suspended 2.29 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. There is friction between
the block and the ramp.
The acceleration of gravity is 9.8 m/s2 . The
pulleys are massless and frictionless.
What is the acceleration of the three block
Answer in units of m/s2
The sum of Fx= N-mgcostheta=o => N=mgcostheta
The sum of Fy= mgsintheta-usN=0=> mgsintheta-us(mgcostheta)
The Attempt at a Solution
are these the correct eqations for this?
