## Homework Statement

1. Homework Statement

There are three blocks on a table. They are connected by a massless cord and pulled to the right. From rigt to left, it follows: T3, block 3, T2, block 2, T1, block 1

m1: 2.5kg

m2: 9.5kg

m3: 1.5kg

mu kinetic: .051

The pulling force is equal to T_3 = 98.0 N. What is the tension T_2?

## Homework Equations

fnet = ma

Fapp(T3) - Fk3 - Fk2 - Fk1 = ma

T2 - Fk2 = 9.5a

## The Attempt at a Solution

well firstly i tried finding the acceleration of the system using all the forces being applied.

i did Tension 3 - all the friction = ma

and acceleration comes out to be 1.336m/s^2

then i sub this back into the 2nd block system equation.

T2 - Fk2 = 9.5a

and Tension2 comes out to be 60.173N.

Is this correct? if i missed a step or did somethign wrong please correct me thanks.
