A sphere of diameter 0.2 m and mass 2 kg is rolling on an inclined plane with velocity v = 0.5 m/s. The kinetic energy of the sphere is :
Text Solution
Verified by ExpertsThe correct answer is:
B
The kinetic energy of sphere while rolling on an inclined plane is given by
E g = Translational kinetic energy + Rotational kinetic energy
= 
mv 2 + 
E K = 
× 2 × (0.5) 2 + 
× 
× 2× (0.1) 2 × 
= 0.25 + 0.17 = 0.42 J
