The position y of a particle moving along the y axis depends on the time t according to(adsbygoogle = window.adsbygoogle || []).push({});

the equation y = at - bt2. The dimensions of the quantities a and b are respectively:

A. L2/T, L3/T2

B. L/T2, L2/T

C. L/T, L/T2

D. L3/T, T2/L

E. none of these

I don't understand what the question is asking, nor do I understand what the variables in the answers represent. Any help making sense of the question and answers is greatly appreciated.
