A spool has a mass of 2 kg,an inner radius `R_(1)` =3cm,and an outer radius `R_(2)= "5cm, the radius of gyration about the axis of the spool is if" =4cm`.A constant horizontal force of 5N is applied to the free end of a massless thread that is wrapped around the inner cylinder of the spool as shownin figure-5.150. If the spool rolls without slipping, calculate the linear acceleration along the horizontal surface. What is the minimum coefficient of static friction required to prevent slipping ?

Answer

`[a=2.139m//s^(2), mu_(min)=0.0062]`
