A 100kg mass starts from rest at the top of an incline plane that makes an angle of 35 degrees with the horizontal, the coefficient of friction of 0.005 between the ramp and the mass. The mass slides down the ramp and then slides to a stop on a surface with coefficient of friction of .9 between the mass and the surface.
How much work is done by the gravitational force while the mass is on an incline?
B) how much work is done by the normal force while the mass is on an incline
c) how much work is done by the frictional force while the mass is on an incline?
D) what is the net work?
E) what is the net force down the ramp?
F how much work was done by the net force while the mass was stil on the incline

Showing your own work would be more effective than posting the same question twice in three minutes, if you hope to elicit a helpful response.
