Answer:
The constant torque required to stop the disk is 8.6 N-m in clockwise direction .
Explanation:
Let counterclockwise be positive direction and clockwise be negative direction .
Given
Radius of disk , r = 1.33 m
Mass of disc , m = 70.6 kg
Initial angular velocity , 
Final angular velocity , 
Time taken to stop , t = 2.75 min
Let
be the angular acceleration
We know

=>
=>
Torque required to stop is given by

where moment of inertia ,
=>
Thus the constant torque required to stop the disk is 8.6 N-m in clockwise direction .

A book weighing 12 N is balanced on a table. Knowing that the static friction coefficient is 0.5, how much is the friction force worth?
Friction force is
f = u * n
f = 0.5 * 12N
f = 60
A) experimental because he isn’t sure and is testing out
