A skier of mass m is sliding down a hill that makes an angle 𝜃 with the horizontal. There is a frictional force of magnitude f resisting the motion of the skier. a) determine the magnitude of the force that the hill’s surface exerts on the skier.
b) Explain what happens to this force as 𝜃 increases.
c) Explain for what value of 𝜃 the force in question maximum.
