## Homework Statement

There's an equilateral triangle with three objects on every corner. Corners named A, B, and C.

The mass of each:

A - 5.5 kg

B - 7.5 kg

C- 10.0 kg

The sides of the triangles are also 5.0 cm each.

There are no other forces acting on the corners. How do I calculate the net force experienced by A due to the other two objects, on corners B and C?

## Homework Equations

Fnet = MA

## The Attempt at a Solution

I couldn't really figure out the question... the only things I did were:

Used Fnet=MA to convert the mass of each corner into newtons

I also realized it was an equilateral triangle, so each corner would be 60 degrees.. and therefore, we could find the exact direction that each corner is pulling towards... not sure if its relevant. They didn't give a mass for the entire triangle either, so I don't think I can find the total mass including the objects at the corners.
