## Homework Statement

We have to find T1 and T2

From right to left objects are: A B C

## Homework Equations

F=ma

## The Attempt at a Solution

Okay. So I found acceleration of whole system:

F=ma

200N= (20+10+5)*a

200/35=a

a= 40/7 ms

^{-2}

Now, finding T

_{1}is fairly simple:

f=ma

T

_{1}=5*(40/7)

T

_{1}=200/7 Newtons (Let's not reduce it right now to decimals)Now, T2. This is where the problem arises.

T2 can be calculated by the difference of the forces on object

**A**.

f=ma

Force on A= 10kg*(40/7)

= 400/7 Newtons

T2 will be:

200-T2= 400/7

200-400/7= T2

1000/7 Newtons= T2

1000/7N= 142.75 Newtons.

Is this answer correct? Please tell me. I'm very confused.

Thank you for reading.
