Respuesta :

The position of the ball at 0.8 s is -12.5 m.

The instantaneous velocity of the ball is calculated using formula,

[tex]v=\frac{d}{t}[/tex]

Plug in the known values,

[tex]\begin{gathered} v=\frac{-12.5\text{ m}}{0.8\text{ s}} \\ =-15.625\text{ m/s} \end{gathered}[/tex]

Therefore, the instantaneous velocity of ball is -15.625 m/s.
