I have 2 questions
1. a block is pulled horizontalls (no acceleration) Find the equation to calculate the normal force and the two coefficents mew static, mew kenetic. assuming u know the mass friction Fs and Fk.
is it just Ff = mewFn all static and Ff = mewFn all kenetic?
and if there is no acceleration then isnt the block standing still?
2. a block slides horizontally with only friction force applied to it ( block already pushed and is slowing down). express the kinetic friction in terms of mass and acceleration. Then determine the coefficient of kinetic friction.
