The acceleration of Moby is 2 m/s²
<u>Explanation:</u>
Given:
Time, t = 5 seconds
Velocity, v = 10 m/s
Acceleration ,a = ?
We know:

On substituting the value we get:

Therefore, the acceleration of Moby is 2 m/s²
I don't know exactly what you are learning, but i know that chemistry involves the practice of mixing chemicals together to see what kind of reaction they make, if they make a reaction at all.
