A ball, which may be approximated as a uniform, solid sphere, rolls without slipping down an incline that makes and angle of $28\mathrm{.}8$ with the horizontal. It is released from rest.

$$ Part $($a$)$

What is the magnitude of the linear acceleration, in meters per second squared, of the ball?

$$ Part $($b$)$

How far, in meters, does the ball roll in $2\mathrm{.}1$s$?$
