Atomic Number: 210
Answer:
Change in velocity is -4m\s
acceleration is -2m\s^2 cause Change in velocity = final v - initial v
Explanation:
Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Thus the SI unit of acceleration is the meter per second squared .
