A string is wrapped around the rim of a wheel of moment of inertia 0.40 kgm ^2 and radius 10 ~cm . The wheel is free to rotate about its axis. Initially the wheel is at rest. The string is now pulled by a force of 40 ~N . The angular velocity of the wheel after 10 ~s is x rad / s , where x is _______

Correct answer

0
