What is the average frictional torque acting on the pulley

Reference no: EM13332215

a) A string passing over a pulley has a 4 kg mass hanging from one end and a 2.5 kg mass hanging from the other end. The pulley is a uniform solid cylinder of a radius 4.3 cm and mass 0.75 kg.

b.) In fact, it is found that if the heavier mass is given a downward speed of 0.21 m/s, it comes to rest in 6.7 s. What is the average frictional torque acting on the pulley?
