3.615 x 10^2 i hope this helps
Answer:13 revolution
Step-by-step explanation:
Given data
Wheel initial angular velocity
=18 rad/s
Contant angular deaaceleration
=2
Time required to stop wheel completely=t sec

0 =18 +
t=9 sec
Therefore angle turn in 9 sec
=
+

=
+

=81rad
therefore no of turns(n) =
n=12.889
13 revolution
