Question

A block of wood of mass 150 g rests on an inclined plane. If coefficient of static friction between the surface in contract is 0.30. find the greatest angle to which the plane may be tilted without the block slipping. ​

Answer 1

Answer:

tan inverse of .3

Explanation:

at max. angle net force in the direction of the slope is zero

mg sin θ= μmg cos θ

tan θ= .3
