## Homework Statement

A block of mass m1 = 3.70 kg on a frictionless inclined plane of angle 30.0° is connected by a cord over a massless, frictionless pulley to a second block of mass m2= 2.30 kg hanging vertically. What are (a) the magnitude of the acceleration of each block and (b) the direction of the acceleration of m2? (c) What is the tension in the cord?

## Homework Equations

F=ma

## The Attempt at a Solution

I set the coordinate system according to the diagram above.

System: m1

Ft+Fg=m1a

Ft-m1gsinθ=m1a

System: m2

Ft+Fg=m2a

Ft-m2g=m2a

Ft=m2g+m2a

Then I plug in both of them.

m2g+m2a+m1gsinθ=m1a

m2a-m1a=-m1gsinθ-m2g

Then I sub in the values

a=3.15?

I don't know what I did wrong. The correct answer is 0.735.
