## Homework Statement

Two blocks, A and B remain stuck together as they are pulled to the right by a force F = 200 N to the horizontal right. B is on a rough horizontal tabletop (coefficiant of kinetic friction is .800)

a) what is the acceleraton of the system

b) what is the force of friction between the two objects?

pic below:

mass of A = 5.00 kg

mass of B = 10.0 kg

## Homework Equations

m A = 5.00 kg

m B = 10.0 kg

F = 200N

kinetic friction = 0.800

## The Attempt at a Solution

a) i already found the acceleration to be 5.5 m/s^2

b) this is where i am STUCK. all i have is the coeff of the friction which is .800

what do i do with it??
