Answer: D. wealthy
Explanation: on the e2020 test its right
Answer:
Angular acceleration will be 
Explanation:
We have given that mass m = 0.18 kg
Radius r = 0.32 m
Initial angular velocity 
And final angular velocity 
Time is given as t = 8 sec
From equation of motion
We know that 


So angular acceleration will be 

The net force acting on the block is ~


So, the Answer in the boxes will be ~
