## Homework Statement

Two blocks of mass m1=80 kg and m2=100 kg and attached by a string, another sting comes off of mass m1 and is pulled horizontally (kinda looks like this) (T1 & T2 are tensions)

m2--T2--m1--T1--> there is a coefficient of friction u=.14 for both blocks, what is the tension in both strings while the system accelerates at 2 m/s^2?

## Homework Equations

Fnet=ma

Ff=u(N)

## The Attempt at a Solution

Ok so for m1 horizontal forces are T1 to the right, T2 to the left and friction.

T2=(100)(9.8)(.14)=137.2 N Friction for m1=(80)(9.8)(.14)=109.8

So T1-T2-Ff = m1*a therefore T1=(80)(2)+(109.8)+137.2= 407 N

Is this Correct??

Thanks!
