Question

The angular speed of the wheels of a bicycle is 8
rad/s. Their period of rotation is​

Answer 1

Given:

Angular speed of wheels is 8 rad/s .

To find:

Period of rotation ?

Calculation:

• We know that complete rotation of circular motion performs 2π radians of angular displacement.

• Now, time taken will be calculated as displacement divided by the angular velocity.

$\therefore \: T = \dfrac{ \theta}{ \omega}$

$\implies \: T = \dfrac{2\pi}{8}$

$\implies \: T = \dfrac{\pi}{4}$

$\implies \: T \approx \: 0.78 \: sec$

So, time period is 0.78 seconds.

Answer 2

Answer:

2π÷8π=4 this answer is correct
