Question

If the angular speed of the wheel of a bicycle is 300 rad/S and radius of wheel is 0.2 m, then linear speed of the wheel of the bicycle is?
A) 90 m/s
B) 60 m/s
C) 30 m/s
D) 15 m/s

Answer 1

Answer:

B) 60 m/s

Explanation:

We have,

Angular velocity= 300 rad/s, radius= 0.2 m

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

Vcm = w*r =300*0.2 = 60 m/s

Hope this helps...

Answer 2

Answer:

B) 60 m/s
