A solid sphere of mass 1 kg rolls down an inclined plane from rest from a height of 7m. On reaching the bottom rotational kinetic energy

K\left( {g = 10\,m{s^{ - 2}}} \right)

View answer and explanation

Correct option: B

20 J

Option B (20 J) is correct because the rotational kinetic energy is 2/7 of the total potential energy converted to kinetic energy.
