A massless rope passes over a frictionless pulley with a radius of 0.15 m. It has a 13 kg mass (ml) on the left and a 2.8 kg mass (m2) on the right, both hanging freely. Initially, 13 kg mass is 2.0 m higher than the 2.8 kg mass. Assuming the system starts from rest and acceleration due to gravity is 9.81 m/s², what is the tension in the rope? Bonus: What is the angular velocity of the pulley when the masses are even with each other? (hint: you will need to use something outside of this unit to answer this.)
thanks!​
