The equation for the change in the position of a train (measured in units of length) is given by the following expression: x = ½ at² + bt³ where a and b are constants and t is time (measured in units of time). If (mass), (length), and (time) represent units of mass, length and time respectively then b must have units of:
(A) (length) / (time)
(B) (length) / (time³)
(C) (mass) (length)
(D) (length) / (mass)
(E) (mass2) (time2)
(F) 1 / (mass) (time)
(G) 1 / (length) (time)
(H) (time) (mass)
(I) (mass) (time2)
(J) 1 / (time³)
(K) (time) / (mass)
(L) (length) / (time²)
(mass) (length2)
