- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Given, Initial velocity of solid spherical ball is v=10 m s-1 Mass of ball rolling on the surface is m=11 kg Applying work energy theorem, W=∆KE Wg=KEf-KEi ...1 Now, initial kinetic energy of spherical ball is Ki=12mv21+k2R2 And final…
