Answer:
Explanation:
= Torque = 36.5 Nm
= Initial angular velocity = 0
= Final angular velocity = 10.3 rad/s
t = Time = 6.1 s
I = Moment of inertia
From the kinematic equations of linear motion we have
Torque is given by
The wheel's moment of inertia is
t = 60.6 s
= 10.3 rad/s
= 0
Frictional torque is given by
The magnitude of the torque caused by friction is
Speeding up
Slowing down
Total number of revolutions
The total number of revolutions the wheel goes through is .
