A student is skateboarding down a ramp that is inclined 20 degrees with respect to the horizontal. The speed of the skateboarder at the top of the ramp is 3.0 m/s and the speed of the skateboarder at the bottom of the ramp is 7.6 m/s. The frictional force between the ramp and the skateboard is 67 N.(adsbygoogle = window.adsbygoogle || []).push({});

(a) If the combined weight of the student and the skateboard is 654 N, determine the acceleration of the student/skateboard system.

I've tried f=ma saying that

(654)-(67) = 654/9.8 [a]

Would that work?
