Question: Consider a tire ( 2 0 kg , and radius of 0 . 3 m ) that is being held above the ground and spinning

Consider a tire

(20

,

and radius of

0.3

)

that is being held above the ground and spinning at a speed of

20

rad

/

.

The tire is then lowered and held against the ground using its own weight but it does not translate forward, it only skids against the ground. Take the coefficient of kinetic friction is

0.5

and the coefficient of static friction is

0.7

and approximate the tire as a hoop. What is the magnitude of the torque applied to the tire due to friction? How long will it take for the tire to stop spinning completely?
