an 85-kg skier is sliding down a ski slope. the slope makes an angle of 23degrees above the horizontal direction.
a) what is the fource actingo n the skier going down the slope?
b) what is the force acting on the skier perpendicular to the slope?
c) neglecting any air resistence the skier is g oing at a constant velocity what is the force of kinetic friction acting on the skier?
d) what id the coefficient of kinetic friction between the skis and the snow?
