Question

If the angular speed of the wheel of the bicycle is 75 rad/s and radius of wheel is 0.8 m, then linear speed of the wheel of the bicycle is

1) 90 m/s

2) 60 m/s

3) 30 m/s

4) 15 m/s​

Answer 1

Answer:

Given :

Angular speed = 75  rad/s

The radius of the wheel = 0.8 m

To answer :

The linear speed of the wheel of the bicycle .

Solution :

Linear speed of an object = ( Angular speed ) * ( Radius )

=> v = ω * r

Now , according to the question ,

=> v = 75 * 0.8

=> v = 60 m/s

The linear speed of the wheel of the bicylce is 60 m/
