Answer:
[tex]5.03\frac{rad}{sec}[/tex]
Step-by-step explanation:
To find the angular velocity divide the revolutions by the time
so
[tex]\frac{16}{20}=0.8\frac{rev}{sec}[/tex]
Remember that
[tex]1\ rev=2\pi \ rad[/tex]
Convert rev/sec to rad/sec
[tex]0.8\frac{rev}{sec}=0.8*(2\pi)=1.6 \pi\frac{rad}{sec}[/tex]
assume [tex]\pi=3.1416[/tex]
[tex]1.6(3.1416)=5.03\frac{rad}{sec}[/tex]
