When q $=35,$ the solid homogeneous cylinder is released from rest on the ramp. Determine the acceleration of the mass center G and the friction force exerted by the ramp on the cylinder if:

$($a$)$ ms $=1\mathrm{.}00,$ and mk $=0\mathrm{.}65,$

$($b$)$ ms $=0\mathrm{.}05,$ and mk $=0\mathrm{.}03.$

Even though you do not need to calculate a$,$ also think about how you can calculate it$.$
