The Force components acting on an object

[Cb8]

Homework Statement

The forces in (Figure 1) act on a 1.4 kg object.

A) What is the value of ax, the x-component of the object's acceleration?

B) What is the value of ay, the y-component of the object's acceleration?

Relevant Equations

F= M•a

Another user suggested adding the forces in the x and y direction then dividing by 1.4.
Doing this for A) gave me 4.285 which was wrong any suggestions?

How about finding the x and y components of the net force?

That suggestion is correct. How sure are you that your work was correct? The suggestion by @Doc Al involves the same procedure as that of the other user up to the point of dividing by 1.4.

1. How did you calculate the value 4.285? I get a different answer. Can you show your steps?
2. Values can be positive or negative so check you are using the correct sign.
3. You need to round your answer to an appropriate number of signficant figures.
4. You need to include the units.
