1. I really don't understand these questions:

1. An object of mass 2kg is acted on by two forces, (1/5) and (5/3)

What is it's acceleration, in vector form, and its magnitude

(1/5) and (5/3) are not fractions they are vectors!

Thank you!

Determine the resultant force.

Use F=ma
3. As RDK said, use

Are the forces i + 5j and 5i + 3j? If so, what is the total force acting on the object?

Determine the resultant force.

Use F=ma
But the answer said to add the forces to get (3/4) and then square root 3^2 add 4^2 to give 5?

No if you add the forces you get (6/8). But the question is not asking for the force, it's asking for the acceleration.

So you have to use F = ma and this is where (3/4) comes from.
