In a bicycle the radius of rear wheel is twice the radius of front wheel. If `v_F` and `v_r` are the speeds of top most points of front and rear wheels respectively, then :

A

`v_(r)=2v_(f)`

B

`v_(f)=2v_(r)`

C

`v_(f)=v_(r)`

D

`v_(f)=4v_(r)`

Text Solution

Verified by Experts

The correct Answer is:
C

The velocity of top point of the wheel is twice that of centre of mass. And the speed of centre of mass is same for both the wheels.

The rear wheel on a clown's bicycle has twice the radius of the front wheel. (a) When the bicycle is moving, is the linear speed at the very top of the rear wheel greater than, less than, or the same as that of the very top of the front wheel? (b) Is the angular speed of the rear wheel greater than, less than, or the same as that of the front wheel?

A wheel is rolling uniformly along a level road (see figure). The speed of transitional motion of the wheel axis is V. What are the speeds of the points A and B on the wheel rim relative to the road at the instant shown in the figure?

A bicycle moves on a horizontal road with some acceleration. The forces of friction between the road and the front and rear wheels are F_(1) and F_(2) respectively.

A wheel of radius R rolls on the ground with a uniform velocity v. The relative acceleration of topmost point of the wheel with respect to the bottommost point is:
