a crate of mass m1 on a frictionless inclined plane is attached to another crate of mass m2 by a massless rope. The rope passes over an ideal pulley so the mass m2 is susupended in the air. The plane is inclined at an angle x=36.9 degree us the conservation of energy to find how fast crate m2 is...
