ANSWER
[tex]43m/s^2[/tex]
EXPLANATION
To find the acceleration of the meteoroid, we have to apply the formula for acceleration:
[tex]a=\frac{v_2-v_1}{t}[/tex]
where v1 and v2 are the initial and final velocities, and t is the time taken
Therefore, we have that:
[tex]\begin{gathered} a=\frac{2.8-1.5}{0.03} \\ a=\frac{1.3}{0.03} \\ a\approx43m/s^2 \end{gathered}[/tex]
That is the acceleration.
