JIPMER2017PhysicsRotational Motion
A bicycle wheel rolls without slipping on a horizontal floor. Which one of the following is true about the motion of points on the rim of the wheel, relative to the axis at the wheel's centre?
Options
- APoints near the top move faster than points near the bottom
- BPoints near the bottom move faster than points near the top
- CAll points on the rim move with the same speed
- DAll points have the velocity vectors that are pointing in the radial direction towards the centre of the wheel
Correct answer
A. Points near the top move faster than points near the bottom
Step-by-step solution
We have, V_A=2 v / 2 Hence, velocity of point on rim increases with for 0^ 180^ and decreases with for 180^ 30^ .
