Hollow Cylinder RollingMediumQuestion 30336
Question
For a hollow cylinder (I = MR²) rolling down a 30° incline, acceleration is: (g = 10 m/s²)
- A2.5 m/s²Correct
- B5 m/s²
- C3.33 m/s²
- D1 m/s²
Correct answer
2.5 m/s²
Explanation
a = g sinθ/(1+k) where k=1 for hollow cylinder. a = 10×0.5/(1+1) = 5/2 = 2.5 m/s².
