Answer:
6.21 seconds
Step-by-step explanation:
The position function of a free-falling object is,
Where,
= initial height of the object,
= initial velocity of the object,
Here,
Hence, the height of the ball after t seconds,
When s(t) = 0,
∵ Time cannot be negative,
Hence, after 6.21 seconds the ball will reach the ground.
