Answer:
Acceleration:
C. Meters per second squared
Velocity:
B. Meters per second
Distance:
A. Meters
Explanation:
We must remember that the international system of measures (SI) takes into account for the length as the main unit the meter, for the mass the kilogram, for the time the second.
The acceleration is calculated using the following expression
a = v/t = (m/s/s) = (m/s^2]
The velocity is calculated using the following expression
v = x/t = (m)/(s) = (m/s)
The distance for the SI system is given in meters
