Rolling MotionMediumQuestion 6143

Question

Acceleration of a sphere rolling down incline (angle θ, no slipping, g):
  1. A
    g sinθ
  2. B
    5g sinθ/7
    Correct
  3. C
    2g sinθ/3
  4. D
    g sinθ/2

Correct answer

5g sinθ/7

Explanation

For solid sphere: a = g sinθ/(1+I/MR²) = g sinθ/(1+2/5) = 5g sinθ/7 = 5g sinθ/7.
