What is the final velocity, in m/s, of a hoop that rolls without slipping down a 5.60 m high hill, starting from rest?

m/s

(b)

What would be the final velocity, in m/s, if a disk of the same mass and radius as the hoop rolled down the hill?

m/s

Step 1

(a)

According to conservation of energy, the potential energy of hoop is converted into kinetic energy.

Step 2

Substitute *rɷ* for *v* in the above equation and solve for velocity.

Step 3

Substituting the...
