A 71.4 skier starts from rest and slides down a 33.0 -m frictionless slope that is inclined at an angle of 18 degrees with the horizontal. Ignore air resistance.
a.) Calculate the work done by gravity on the skier and the work done by normal force on the skier.
Wgravity = ____kJ
Wnormal =_____kJ
b.) If the slope is not frictionless so that the skier has a final velocity of 11.3 m/s, calculate the work done by gravity, the work done by normal force, the work done by friction, the force of friction (assuming it is constant), and the coefficient of kinetic friction.
Wgravity =____kJ
Wnormal =____kJ
Wfriction =____kJ
Ffriction =____kJ
