my way:

T1=24.5N θ=30

T2=42.7N θ= -60

m=?

m=Fnet/a

the ans should be (m=5.017 Kg)

How many forces act on the mass?

3 forces

Fg and 2 tension forces

Fg and 2 tension forces

Now find the vertical components of the two tensions.

T1: 24.5 sin 60=21.21N

T2: 42.7 sin 30=21.35N

T2: 42.7 sin 30=21.35N

T1: 24.5 sin 60=21.21N

T2: 42.7 sin 30=21.35N

If you draw a diagram you will notice that the above are the HORIZONTAL components.

(Incidentally, the horizontal components must be equal in magnitude)
