A jogger is going around a circular track with a radius of 100 ft. Determine the
1 answer:
Answer:
ω= 0.01 rad/s
Step-by-step explanation:
The given data is question is ,
- r = 100ft .
- t = 3 min = 180s.
Firstly let's find the linear speed. Which is
=> v = Circumference/time
=> v = 2πr/180s
=> v = 3.14 × 100ft ./ 90
=> v = 3.48 ft/s ≈ 1m/s
- Now the angular speed and linear speed are related as follows ,
=> v = r
=>
= v/r
=>
= 1/100
=>
= 0.01 rad/s
<h3>
<u>Hence </u><u>the</u><u> </u><u>angular</u><u> speed</u><u> </u><u>is </u><u>0</u><u>.</u><u>0</u><u>1</u><u> </u><u>rad/</u><u>s.</u></h3>
