Answer:
Explanation:Hooke's law states that " if the elastic limit of an elastic material is not exceeded, the extension,e is directly proportional to the applied force or load.
Answer
given,
initially rotating speed = 130 rad/s
final rotating speed = 0 rad/s
constant acceleration = 3 rad/s²
a) using equation of rotating acceleration


3 t = 130
t = 43.33 s
time does the disk take to stop is equal to 43.33 s
b) again using equation of rotation



angle does the disk rotate during that time is equal to 2817 rad
