a t = b t^2 + c t^3 + d
a t is (force * distance / time) *time
= m L/T^2 * L = m L^2/T^2
the other terms must have the same
so b T^2 = m L^2/T^2
b has dimension m L^2/T^4
c T^3 = m L^2/T^2
c has dimensions m L^2/T^5
d is m L^2/T^2
by the way since a has dimensions of power then a t has dimensions of work or energy (Joules)
d has dimensions
