Answer:
L/T^2.
Explanation:
Dimensional analysis is defined as the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, temperature etc.) and units of measure (such as miles vs. kilometers, pounds vs. kilograms etc.).
F = m * a
kg(m/s^2) = kg * a
In dimensions,
a = L/T^2.
