A 100 kg mass starts from rest at the top of an incline plane that makes an angle of 35 degrees

Question

with the horizontal. There is a 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 that the coefficient of
friction is 0.9, between the mass and the surface. ( 72 Points, 6 Each )
a.) How much work is done by the gravitational force while the mass is on the incline?
b.) How much work is done by the normal force while the mass is on the incline?
c.) How much work is done by the frictional force while the mass is on the incline?
d.) What is the net work ( sum of the work ) done while the mass is on the incline?
e.) What is the net force down the ramp?
f.) How much work was done by the net force while the mass was on the incline?
g.) How far does the mass slide along the horizontal surface before coming to rest?
h.) How much work is done by the gravitational force during that slide?
I.) How much work is done by the normal force during that slide?
j.) How much work is done by the frictional force during that slide?
k.) What is the net work done on the mass during that slide?
l.) What is the change in kinetic energy of the block during that slide?
