A particle is revolving uniformly at 170rad/s is brought to rest by a uniform angular retardation `alpha=5(rad)/s^(2)`. The time require to stop is __________

A flywheel is revolving at 150 revolutions per minutes .If deccelerates at a constant rate of 2 pi rad //s^(2) , then time requred to stop it is

A wheel starting from rest is uniformly acceleration with angular acceleration of 4 "rad"//s^(2) for 10 seconds . It is then allowed to rotate uniformly for next 10 seconds and finally brought to rest in next 10 seconds by uniform angular retardation. Total angle rotated is (100 n) radian. Find value of n.
