Compute all parts of following problem given below:
Problem: A 30.0-kg block is initially at rest on a horizontal surface. A horizontal force of 76.0 N is required to set the block in motion, after which a horizontal force of 58.0 N is required to keep the block moving with constant speed.
Part A: Find the coefficient of static friction between the block and the surface.
Part B: Find the coefficient of kinetic friction between the block and the surface.
I need help to find the coefficient of kinetic friction between the block and the surface.
