A horizontal force of 75.0 N is required to set the block in

motion, after which a horizontal force of 60.0 N is required

to keep the block moving with constant speed. Find (a) the

coefficient of static friction and (b) the coefficient of

kinetic friction between the block and the surface.

2. Homework Equations

**3. i need help setting up the problem. i would apply the net force model for the x direction and equilibrium model for the y model. i need to know if this is right.**

Fx = 75.0N - F(static) - 60.0N = ma

Fy = n - mg = 0

Fx = 75.0N - F(static) - 60.0N = ma

Fy = n - mg = 0
