R = 12 cm
M = 2 kg tox4hnaq.2fu.png

(a) Write an expression for the ring's initial energy at point 1, assuming that the gravitational potential energy at point 3 is zero.

(b) If the ring rolls (without slipping) all the way to point 2, what is the ring's energy at point 2 in terms of h2 and v2?

(d) What is the ring's rotational velocity in rad/s?

(e) After passing point 2 the hill becomes frictionless and the ring's rotational velocity remains constant. What is the linear velocity of the ring at point 3 in m/s?
