Question

A skier starts from rest at point A and slides down the hill without turning or breaking. The friction coefficient is $μ$. When he stops at point B, his horizontal displacement is S. What is the height difference between points A and B?
(The velocity of the skier is small so that the additional pressure on the snow due to the curvature can be neglected. Neglect also the friction of air and the dependence of $μ$ on the velocity of the skier.)

• A. $h=μS$
• B. $h=\frac μS$
• C. $h=2μS$
• D. $h=μS^2$

Answer 1

Answer: (A)

$h=μS$

Answer 2

The correct option is (A): $h=μS$.
