The ratio of the accelerations for a solid sphere rolling down an incline of angleФ slipping and slipping down the incline without rolling is?



The fastest order is solid sphere, disc, hollow sphere, this is because of the inertia 

solid sphere = 0.7mv^2 = mgh 

disc = 0.75mv^2 = mgh 

hollow sphere = 0.833mv^2 = mgh 

solid sphere velocity = sq-root((gh)/0.7) 

disc velocity = sq-root((gh)/0.75) 

hollow sphere velocity = sq-root((gh)/0.833)
