(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In the ideal setup showin in the following figure, M1=3.0 kg and M2=2.5KG

A) What is the acceleration of the 2 mass system?

B) What is the tension in the string?

2. Relevant equations

Asys=M2 * g - M1 * g (sin[tex]\oslash[/tex]) / M1 + M2

3. The attempt at a solution

Calculated the acceleration of the system using above equation and obtained:

Asys=1.24 m/s^2

My teacher gave me full credit onthatpart of my answer. On part B, however, I was expected to find the tension on the string. Here's what I attempted:

Asys=M1(g) -T / M1

1.24 m/s^2 = 2.5(9.8) - T / 5.5 kg

I am thinking I need to also divide by mass 2? Either way, I think I could use a fresh approach at thinking about tension. To me, it just seems like the transferred force through a string....I guess I'm a bit confused.

Thanks in advance,

Ian
