Acceleration is the rate of change of velocity of an object. Thus when the velocity ( direction or magnitude) of an object changes, we say that the particle is accelerating. Mathematically it is written as
a= 
The units of acceleration are m/s²
Acceleration can be positive or negative. If the velocity of an object increases, we call that as positive acceleration and if the velocity of an object decreases, we call that as the negative acceleration.
Answer:
500km/h
Explanation:
I don't know what units you need the answer in, but if the units were to stay the same, then that's the answer^.
We don't know the question you're talking about, hun.
