Answer:
0.027m/s²
Explanation:
Acceleration (in its simpler form) is defined as the change in velocity divided by the interval of time in which occurred that change. Mathematically:
\(a=\frac{v_{2}-v_{1} }{t}\)
Where:
\(v_{1}\): initial velocity
\(v_{2}\): final velocity
t: time needed to that increase in velocity
Plugging the given values in the equation:
\(a=\frac{3.5m/s-31m/s}{15s}\)
\(a=\frac{0.4m/s}{15s}\)
a= 0.027m/s²
So, her acceleration during her big push was 0.027m/s²
