variable	quantity	SI unit
\( N =mg \; \\cos{(25^{0})} \)	Normal force which is equal to the component of weight perpendicular to the incline plane (perpendicular to the \(x-axis\)).	\( N \)
\( mg \; \\sin{(25^{0})} \)	Component of weight parallel to the incline plane (parallel to the \(x-axis\)).	\( N \)
\( f =\mu_{k} \; N\)	Kinetic friction	\( N \)
\( mg \; \sin{(25^{0})} - f \)	Net force driving the skier down the plane.	\( N \)
\( \Large a = \frac{mg \; \sin{(25^{0})} - f }{m} \)	Acceleration of the skier down the plane.	\( m/s^2 \)
