Two blocks of masses m1 and m2 are placed on a table in contact with each other as shown in the figure below. The coefficient of kinetic friction between the block of mass m1 and the table is μ1, and that between the block of mass m2 and the table is μ2. A horizontal force of magnitude F is applied to the block of mass m1. We wish to find P, the magnitude of the contact force between the blocks.
What is the magnitude P of the contact force between the blocks in terms of the same quantities?
write Newton's second law in the x direction for each block.

Question

Two blocks of masses m1 and m2 are placed on a table in contact with each other as shown in the figure below. The coefficient of kinetic friction between the block of mass m1 and the table is μ1, and that between the block of mass m2 and the table is μ2. A horizontal force of magnitude F is applied to the block of mass m1. We wish to find P, the magnitude of the contact force between the blocks. 
What is  the magnitude P of the contact force between the blocks in terms of the same quantities?
write Newton's second law in the x direction for each block.

find the net acc. by:

F-u1*m1g - u2*m2g = (m1+m2)a

use 'a' to find:

P -u2m2g = m2a

ummm, the P=m2(a+u2g) 
is not correct according to the webassign

gj following instructions.  another alternative is to just assume any equation you're given on this site is an answer and copypasta it into webassign or whatever multiple guess site you happen to be using.
