Answer: (3) 0.44 rad/s, 5.28 cm/s
- Circular groove of radius = 12 cm
- Insects completes 7 revolutions in 100 sec
The time period of revolution can be calculated as
T = 100/7 sec
Angular speed
We can calculate the angular speed using this time period formula as
\(\begin{array}{l}omega = frac{2pi }{T}\end{array} \)
⇒
\(\begin{array}{l}omega = frac{2times frac{22}{7} }{frac{100}{7}}\end{array} \)
ω = 0.44 rad/sec
Linear speed
We can calculate the linear speed using the formula
Linear speed = rω
Linear speed = 12 × 0.44
Linear speed = 5.28 cm/sec
