Reference no: EM131712567

A heavy flywheel, rotating initially at 1500 rpm is allowed to slow down to 1120 rpm in 10.2 minutes due to air and bearing friction. It is then brought to rest by the application of a brake which caused an angular deceleration of 1.15 rad/s2. Calculate

i) the total time in minutes and

ii) the total number of revolutions to come to rest from 1500 rpm
