Dear student
 
dimensions of F/t = dimension of Av^2 = dimension of Bt
 
[MLT^-2] /[T] = A [L^2 T^-2] = B [T]
 
A = [ML^-1 T^-1]
B = [MLT^-4]
 
Hope it helps

Dear student 
Please follow this for better understanding 
 
Since, the force is on the left hand side, therefore the right hand side quantities also represent force.  Thus, both at and bt² represent force.  
Dimensional formula of force -  M L T^(-2)  
Dimensional formula of at and bt² will also be M L T^(-2)  
Means, [aT] = MLT^(-2)  
= [a] = (M1 L1 T-²)/T  
= [a] = M1 L1 T-³  
Similarly for B,  
force = Bt²
so b= force/t2
= MLT^-4
Hope this clear
