Find coefficient of static friction between block-surface

Reference no: EM13536613

A28.0-kg block is initially at rest on a horizontal surface. A horizontal force of76.0N is required to set the block in motion, after which a horizontal force of57.0N is required to keep the block moving with constant speed.

a) Find the coefficient of static friction between the block and the surface.

b) Find the coefficient of kinetic friction between the block and the surface.
