problem statement, all variables and given/known data

A pair of blocks are connected by a massless rope and placed on a frictionless surface. The diagram shows the situation at the instant the blocks are released. The left side has a mass of 35 kg and an incline of 25 degrees to the horizontal. The right side has a mass of 20 kg and an incline of 40 degrees to the horizontal.

## Homework Equations

## The Attempt at a Solution

My attempt was solving each blocks acceleration by doing

Σf(+x)= Fgsin(theta)=ma

fg = mg there fore mgsin(theta)=ma

the masses cancel out leaving

gsin(theta)=a

so acc of block 1 =

(9.8m/s^2)(sin(25))=4.142 m/s^2

Should I not be canceling the masses out?

Would a better approach be taking mgsin(25)-mgsin(40)/55 = 0.345s?
