Questions
A block has been placed on an inclined plane. The slope angle of the plane is such that the block slides down the plane at a constant speed. The coefficient of kinetic friction is equal to
detailed solution
Correct option is D
Angle of plane is just equal to the angle of repose.i.e. μk .mg cos θ = mg sin θ ⇒μk=tan θHence, the coefficient of kinetic friction, μk= tan θTalk to our academic expert!

A skier starts from rest at point A and slides down the hill without turning or breaking. The friction coefficient is . 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 on the velocity of the skier.)
