Question

a) Calculate 1+ICM/(MR2) for a solid disk, like the 1st boy rolled in the race.

b)Calculate 1+ICM/(MR2) for a hollow cylinder, like the 2nd and 3rd boys rolled in the race.

c) Calculate 1+ICM/(MR2) for a solid sphere, like the 4th boy rolled in the race.

(equation for disk: 1/2 MR^2)

(equation for cylinder: I = 1/2 MR^2)

(equation for sphere: I = 2/5 MR^2)
