A cord passing over a pulley connects two masses, as shown, where
m1 = 3.60 kg
and
m2 = 7.10 kg.
The system accelerates with a magnitude of 0.99 m/s2. The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless.
