2) During an experiment, a student set up a system shown below. She used an ideal light string and a frictionless pulley with diameter 12 cm for this set up. Then she found the moment of inertia of the pulley as 60 kg. cm2 and the coefficient of friction for the table as 0.30. Then she released blocks from rest and while the 3 kg block moved forward, the 2kg block descended. Find the speed of 2kg block when it descended 0.5 m from rest. 3 kg 23 kg
