Q:

A golfer’s arm rotates 1/2 of a revolution in 1/10 of a second. If the angular displacement is measured in radians, which statements are true? Check all that apply. The angular velocity is 10π rad/sec. multiple can be chosen 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.

Accepted Solution

A:
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.
