here is your answer

hope its help you

Answer 2

Answer:

39.2 m/s

Step-by-step explanation:

The velocity of the stone is given by the velocity function

$v=9.8t$

where v is velocity of the stone after t seconds.

We need to find the velocity of the stone '4' second after start.

Substitute t=4 in the given velocity function.

$v=9.8(4)$

$v=39.2$

Therefore the velocity of the stone '4' second after start is 39.2 m/s.
