Question

a wheel starting from rest acquires and angular velocity of 10 radian per second into seconds the moment of inertia of the wheel is 0.4 km square calculate the torque acting on it

Answer 1

T=I*alpha

Alpha =change in velocity /time

V=10 radian/sec

U=0 radian /sec

M.I=0.4kmsq.

Time=1sec
