Similar to last homework, an object m = 3.25kg rolls from rest down an incline plane, its center initially at a height of 8.05m above the bottom of the ramp. The inclination of the incline as measured from the horizontal is 39.3^o. If the object is a solid uniform cylinder of radius r = 1.35m, then at the bottom of the incline, what is the (a) rotational kinetic energy and (b) the angular momentum. If the object is a hoop of radius, r = 1.15m, then at the bottom of the ramp, what is the (c) rotational kinetic energy and (d) the angular momentum?

a) ______ J

b) ______ kgm^2/s

c) _______ J

d) ________kgm^2/s
