Question 88

Multiple Choice

A solid sphere of radius r = 5 cm and mass m = 0.2 kg rolls in a groove as shown. The angle, $\theta$ , between the points of contact with the groove is 120^$\circ$. If the sphere has a linear velocity of 10 mm/s, what is the rotational kinetic energy? $A solid sphere of radius r = 5 cm and mass m = 0.2 kg rolls in a groove as shown.
