Homework Statement
A wheel decellerates from 100 rpm in 10 sec. Find angular acceleration, torque and the force torque is producing on a fixed object.
The wheel has a radius of .0025m and a mass of 50kg.
Homework Equations
T=Ia
a=ra
T=dL/dt
The Attempt at a Solution
The first thing I did was change rpm to rad/sec which gave me 10.5 rad/sec.
for angular acceleration i used: a=ra-> .0025*10.5/10 which gave me
a=.002625 rad/sec^2.
For torque i used 1/2*50*.0025^2*1.05 which gave me .00016 kgm^2.
I am not sure where to go with this now, or even if I am headed in the right direction. Any suggestions would be greatly appreciated.
