Physics Question:
A wheel has a radius of .5 m and a moment of inertia I = 3kgm^2. It is rotating at 20 rev/s about an ais through its centerwhen a stick, acting as a brake, is applied to the outer edge. Itis brought to rest in 30 seconds
a.) Find the angular acceleration of the wheel
b.) How many revolutions does it make before coming to rest?
c.) How much kinetic energy does it lose in coming to rest?
d.) How much force did the stick exert on the wheel?
e.) Find the linear distance covered by a speck of dust, locatedhalfway between the center of the wheel and the outer edge, duringthe time the wheel was coming to rest
