RSL-7 A yo-yo consists of two identical disks of radius R2, each of mass mD, connected by a short shaft of negligible mass. A string is wrapped around the shaft, which has a radius R1 as shown to the right. The top of the string is held at rest and the yo-yo is allowed to drop. Side view: End view: string R2 a) Apply Fnet-ma and Tner-la to find the magnitude of the linear acceleration of the yo-yo center. b) Find the speed V2 of the yo-yo center after it has gone down a distance d.

Macmillan Learning The Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. Approximate the pulley as a uniform disk with mass m₂ = 5.13 kg and radius rp=0.450 m. The hanging masses are m = 20.7 kg and mg = 12.7 kg. Calculate the magnitude of the masses' acceleration a and the tension in the left and right ends of the rope, 7₁, and TR. respectively. a= TL = TR = 2 m/s N m₁ 111
