sorry for not using the forum
but a block of wood he's a mass of 5Kg is at rest on a horizontal surface. a spring scale is slowly pulled until the block just begins to move. at this point a reading on the scale is 29N. after the block starts sliding the reading on the scale is 23N.
A) what is the normal foce?
B)what is the frictional force?
C) what is the coefficient for static and kinetic friction on the horizontal?
what is the answer and how do you get the friction without the coefficeint?
