Answer:
[tex] - 4 \: m {s}^{ - 2} [/tex]
Step-by-step explanation:
Initial velocity u = - 2 m/s
Final Velocity v = - 10 m/s
Time t = 4
[tex]Acceleration = \frac{Change \: in \: velocity}{time} \\ = \frac{v - u}{t} \\ = \frac{ - 10 - ( - 2)}{t} \\ = \frac{ - 10 + 2}{t} \\ = \frac{ - 8}{2} \\ = - 4 \: m {s}^{ - 2} \\ [/tex]
