Can anyone confirm/deny that if an object is dropped (init. velocity=0) that it will take about 2.26 seconds to reach 90 km/h?(adsbygoogle = window.adsbygoogle || []).push({});

[tex]S=\frac{D}{T}[/tex]

[tex]A=\frac{V_f-V_i}{T_f-T_i}[/tex]

[tex]D=\frac{1}{2}gT^2[/tex]

[tex]V_f^2=V_i^2+2a(X_f-X_i)[/tex]

[tex]\overline{V}=\frac{V_f+V_i}{2}[/tex]
