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

A figure shows two blocks connected by a cord that passes over a frictionless pulley. The arrangement is known as Atwood's machine. Block 1 has mass m1 = 1.30 kg; block 2 has mass m2 = 2.80 kg.

Sorry, no picture.

What is the magnitude of the acceleration of the blocks?

2. Relevant equations

T = 1.3a + 12.7 N

T = -2.8a + 27.4 N

3. The attempt at a solution

The answer is 3.58 m/s^2 but why and how?
