Question

If the angular speed of the wheel of the bicycle is 300 rad/s and radius of the wheel is 0.2 m , then what is the linear speed of the wheel of the bicycle ??​

Answer 1

Answer:

60 m/s

Explanation:

1) We have,

$Angular\:velocity, \omega = 300 rad/s\\ \\ radius,r=0.2m$

Now, we need to find Linear speed of the vehicle ,that is speed of centre of mass of the  bicycle:

$v_{cm}=\omega r =300*0.2=60 m/s$

Hence, Linear speed of the wheel of the bicycle is 30 m/s.

Note : Above velocity is at the instant,at the given angular velocity.
