Physics :-
A cyclist moving with a uniform speed of 36km /h . If the radius of each wheel is 0.25 m, calculate the angular speed of wheels.

Answer 1

Solution :-

We will be using this in order to Solve :-

• v = 2πr/T

• and Omega = 2π/T

Here

• Omega = angular velocity of the particle

• v = linear velocity of particle / velocity

• r = radius of particle

Now we have

r = 0.25 m

v = 36 km/h or

= 36 × 5/18

= 10 m/s

Now by putting the value :-

v = 2πr/T

→10 m/s = 2π(0.25)/T

→10 /(0.25) = 2π/T

→10 × 100/25 = 2π/T

→40 = 2π/T

Now as

Omega = 2π/T

→ Omega = 40

So angular velocity = 40 radians /sec
