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:
200T2= 400/7
200400/7= 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.
