1. Vector sum of forces:

The the acceleration

2. let the tension be then the total force on the first particel, and hence the acceleration is:

and for the second particle:

but so:

which can then b solved for

Start by drawing a Free-Body-Diagram for the ball.

I have a +x axis to the right and a +y axis upward. There is a weight (w) acting straight downward, a tension (T) acting at 50 degrees above the -x axis, and an applied force (F) of 50 N acting in the +x direction.

Since the ball is in equilibrium we know that

So:

which implies

and

which implies
