Ответ:
We use the kinematic equation of motion, to calculate the average acceleration
or![a=\frac{v^{2} -v_{0}^2}{2(h-h_{0}) }](/tpl/images/0078/0674/80a1d.png)
Here,
is initial speed , v is final speed h is covered distance
is initial position.
Given
,
,
and
.
Substituting these values in above equation we get,
Thus, the average acceleration of the sprinter is
.
