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? A bicycle wheel rolls without slipping on a horizontal floor. Which one of the following is true about the motion of

Options

  1. APoints near the top move faster than points near the bottom
  2. BPoints near the bottom move faster than points near the top
  3. CAll points on the rim move with the same speed
  4. 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, VA=2vsin⁡θ/2V_A=2 v \sin \theta / 2 Hence, velocity of point on rim increases with θ\theta for 0∘<θ<180∘0^{\circ} \lt \theta \lt 180^{\circ} and decreases with θ\theta for 180∘<θ<30∘180^{\circ} \lt \theta \lt 30^{\circ}.A bicycle wheel rolls without slipping on a horizontal floor.
