Cricetus

Answer:

The appropriate answer is "0.9152 seconds".

Explanation:

The given values are:

Maximum speed,

v = 8.85 m/s

Acceleration,

u = 9.67 m/s²

Now,

⇒ [tex]v = u+at[/tex]

By putting the values, we get

⇒ [tex]8.85=0+9.67t[/tex]

⇒      [tex]t=\frac{8.85}{9.67}[/tex]

⇒         [tex]=0.9152 \ second[/tex]
