Answer 2

Answer:

m/s²

Explanation:

retardation is just an acceleration,only difference is that it is opposite to the direction of motion.

for example if a body is moving in X axis ,and a force is also applied in the same X direction, it's acceleration.

in case force is applied in negative X axis then we call it retardation.
