Question

A runner starts from rest and achieves a maximum speed of 8.85 m/s.

Answer 1

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,

⇒ $v = u+at$

By putting the values, we get

⇒ $8.85=0+9.67t$

⇒      $t=\frac{8.85}{9.67}$

⇒         $=0.9152 \ second$
