right side and speed? Two masses of 6.3kg and 2.6 kg are suspended by a pulley with a radius of 13 cm and a mass of 3 kg. The cord has negligible weight and causes the pulley to rotate without slipping.
1) What is the angular acceleration of the pulley? Treat the pulley as a uniform disk. The acceleration of gravity is 9.8 m/s^2. Answer in units of rad/s^2.
2) What is the magnitude of tension in the cord on the right-hand side? Answer in units of N.
3) The masses start from rest 2.14 m vertically apart. What is the speed of the right-hand mass when the two masses pass each other? Answer in units of m/s.

The diagram given shows the 6.3 kg mass 2.14 m higher than the 2.6 kg mass. The 6.3 kg mass is on the right with the 2.6 kg mass on the left. Also shows w with an arrow to the left, towards the 6.3kg mass.
