m1=6kg

m2=3kg

r=0.25m

Alright so my three equations are:

T=m2(a-g)

F=T-m1a

FR=m1r^2(a/r)

Substituting:

m1r^2(a/r) = (m2(g-a))-m1a (r)

6(0.25)^2(a/0.25) = (3(9.8-a))-6(a)(0.25)

1.5a = 29.4-3a-6a (0.25)

1.5a = -2.25a + 7.35

3.75a = 7.35

a= 1.96m/s^2

then:

T= m2(a+g)

T= 3(1.96+9.8)

T= 35.3N
