(8%) Problem 11: A thin cylindrical ring starts from rest at a height h = 94 m. The ring has a radius R = 28 cm and a mass M= 2 kg. R ▷ A 20% Part (c) Given h₂ = 44 m, what is the velocity of the ring at point 2 in m/s? h 2/₂ = 2 ✓20% Part (a) Write an expression for the ring's initial energy at point 1, assuming that the gravitational potential energy at point 3 is zero. E₁ Mgh ✔Correct! ✓20% Part (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? E₂=Mv₂²+Mgh₂ ✓ Correct!
