Answer:
[tex]a=500m/s^2[/tex]
Explanation:
We need only to apply the definition of acceleration, which is:
[tex]a=\frac{v_f-v_i}{t_f-t_i}[/tex]
In our case the final velocity is [tex]v_f=10m/s[/tex], the initial velocity is [tex]v_i=0m/s[/tex] since it departs from rest, the final time is [tex]t_f=0.02s[/tex] and the initial time we are considering is [tex]t_i=0s[/tex]
So for our values we have:
[tex]a=\frac{10m/s-0m/s}{0.02s-0s}=500m/s^2[/tex]
