A 4-kg block rests on a horizontal surface. The block is pulled by 20 N force acting 25⁰ above the horizontal but not enough to move the block. Calculate the following: (a) the friction force between the surface and the block. (b) the normal force on the block. (c) the coefficient of static friction.
