A flywheel rotates with a constant retardation due to braking. From
t=0
to
t=10
seconds, it made 300 revolutions. At time
t=7.5sec
its angular velocity was
40\pi ra(d)/(sec)
. Determine (
i
) value of constant retardation; (ii) total time taken to come to rest and (iii) total revolutions made till it comes to rest.
