Question

A block placed on an inclined plane of slope angle θ slides down with a constant speed. The coefficient of kinetic friction is equal to

Answer 1

Answer:

then the friction force f=μN

Now , normal force N=mgcosθ so f=μmgcosθ

In equilibrium, mgsinθ=f=μmgcosθ or μ=

cosθ

sinθ

=tanθ

solution
