Each year at a college, there is a tradition of having a hoop rolling competition. Alex rolls his 0.25 kg hoop down the course. If the hoop has a radius of 0.5 m, what is the moment of inertia of Alex’s rolling hoop?
Answer:
m=mass=o.25 kg ; r=radius=0.5 m
.
For a hoop:
.
Moment_of_Inertia=mr%5E2
.
Moment_of_Inertia=%280.25kg%29%280.5m%29%5E2
.
Moment_of+_inertia=%280.25kg%29%280.25m%5E2%29
.
Moment_of_Inertia=0.0625 kg/square meter
