Answer:
c = -4
Step-by-step explanation:
16 = 4 - 3c
subtract 4 from each side
16-4 = 4-4 - 3c
12 = -3c
Divide each side by -3
12/-3 = -3c/-3
-4 =c
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
