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

Two objects are connected by a light string that passes over a friction less pulley as shown in the figure below. Assume the incline is friction less and take m1 = 2.00 kg, m2 = 7.75 kg, and θ = 55.5°.

From this information, I have to determine the acceleration and tension of the string.

2. Relevant equations

3. The attempt at a solution

I attached the diagram and my work as files.

I used the last formula to find the acceleration. I plugged in the values, and got [itex]a = \frac{7.75cos(34.5)-2.00(-9.8)}{2.00+7.75}[/itex], which simplifies to 2.67 m/s^2. The actual answer is 4.41 m/s^. Can anyone account for this difference?
