A solid sphere, a solid disk, and a thin hoop are all released from rest at the top of the incline (h0 = 20.0 cm).
Required:
a. Without doing any calculations, decide which object would be spinning the fastest when it gets to the bottom. Explain.
b. Again, without doing any calculations, decide which object would get to the bottom first.
c. Assuming all objects are rolling without slipping, have a mass of 2.00 kg and a radius of 3.00 cm, find the rotational and translational speed at the bottom of the incline of any one of these three objects.
