I am stuck on a piece of my homework assignment(adsbygoogle = window.adsbygoogle || []).push({});

here it is

The following equations describe the motion of a system of two objects.

FN - (6.50 kg)(9.80 m/s2) cos(13.0˚) = 0

Ff,k = 0.360(FN)

FT + (6.50 kg)(9.80 m/s2) sin(13.0˚) - Ff,k = (6.50 kg) a

-FT + (3.80 kg)(9.80 m/s2) = (3.80 kg) a

(a) Solve the equations for a and FT. (b) Draw a free-body diagram for both objects. (c)

Describe a situation to which these equations apply.

I have solved for FN and then solved for Ff,k using that information

FN=62.07N and Ff,k+22.35 N (assuming i did my algebra correctly)

form here i know if i solve for acceleration of Ftension i can solve for the other.

I tried using a system of equations to solve for "a" by solving for Ft in on equation and plugging it into to other. when i do that i end up with the variable im solving for cancelling out.

Any suggestions?
