Questions
A block of mass 2 kg is sliding down a rough inclined plane having inclination with constant velocity of 0.5 m/s. Then coefficient of kinetic friction between the block and the same is
detailed solution
Correct option is A
(1)Since velocity of the block is constant,mgsinθ−fk=0 ⇒ mgsinθ −μk.mgcosθ=0 ⇒ μk=tanθ∴ μk=tan300=13 =0.577.Talk to our academic expert!
