A $2\mathrm{.}00$ kg block is placed on an inclined plane and released from rest. The coefficients of static and kinetic friction between the block and the incline are $0\mathrm{.}500$ and $0\mathrm{.}100,$ respectively.

$($a$)$ If the angle of incline is $15\mathrm{.}0$ degrees, what is the force of friction on the block after it is released? What is the magnitude of its acceleration?

$($b$)$ If the angle of incline is increased to $35\mathrm{.}0$ degrees, what is the force of friction after release? What is the magnitude of its acceleration?
