Answer #1

F = Force applied

f = frictional force

by knowing acceleration of object moving and solving we can get.

This way we can find co-efficient pf kinetic friction.

If we want to find static co-efficient of friction between A and B then put A on top of B and start inclining B, check the angle of surface B when A starts (just) sliding on B.

This angle is angle of repose.

considertangent of this angle.

actually because this will give static co-efficient of friction when A starts just to slid on B, that time tangent of inclination angle of B is equal to the static co-efficient of friction between A and B.
