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.
(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?
