A)The angular velocity is 10π rad/min.
B)The angular velocity is 60π rad/min.
C)The angular velocity is 600π rad/sec.
D)The angular velocity is 600π rad/min.

we know that

The angular velocity is 10π rad/sec
step 1
convert to rad/min
1 min-----60 sec
X min----> 1 sec
X=1/60 min
V=10π rad/(1/60)------> V=600 π rad/min

the answer is the option 
D)The angular velocity is 600π rad/min.

Answer:

A and D

Step-by-step explanation:

a)

[tex]\frac{.5 rev}{.1 }[/tex] = 5 rev/sec

-- Convert to radians

[tex]\frac{5 rev}{1 sec} * 2\pi =10 \frac{radians}{sec}[/tex]

d)

[tex]10\frac{rad}{sec}*\frac{60 sec}{1 min}[/tex]  = 600 rad/min
