Question

PLEASE HELP ME ANSWER THIS ASAP! !​

Answer 1

-4 m/s and -2 m/s2

:-)

Answer 2

Change in velocity is -4m\s

acceleration is -2m\s^2 cause Change in velocity = final v - initial v

Step-by-step 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 .
