(II) A grinding wheel is a uniform cylinder with a radius of8.50 cm and a mass of 0.380 kg. Calculate (a) its moment ofinertia about its center, and (b) the applied torque neededto accelerate it from rest to 1750 rpm in 5.00 s. Take intoaccount a frictional torque that has been measured to slowdown the wheel from 1500 rpm to rest in 55.0 s.

Given radius of the cylinder= 8.50cm mass= 0.380 kg 1750 rpm in 5.00s 1500 rpm in 55..0 s
