A solid cylinder (1 =1/2mr2 ) with a mass of 4.83 kg and a radius of 0.057 m starts
from rest at a height of 4.10 m and rolls down a 30.5 degree slope without
slipping. What is the translational (linear) speed of the cylinder when it leaves the
incline? (Hint: This is not an angular momentum problem. The obvious solution is
COE.)

In a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea’s vertex is focused on the retina?
