As you have Force on Left Hand Side, the right hand side quantities also represent force....so at and bt2 represent force.....
but dimensional formula of force is
Force: M1 L1 T(-2)
so, dimensional formula of at and bt 2 is also M1 L1 T(-2)
Means, [aT] = M1 L1 T(-2)
SO, [a] = (M1 L1 T(-2) )/T
so [a] = M1 L1 T(-3)
Same way for b,
bt2 = force
so b= force/t2 = M1 L1 T(-4)
