The final velocity of the ball at the end of 6 seconds is approximately 58.86 m/s.

Distance fallen (s) = (1/2) * acceleration (g) * time (t)^2

Final velocity (v) = initial velocity (u) + (acceleration * time)

Given that the ball is in free fall, its initial velocity (u) is 0, and the acceleration due to gravity (g) is approximately 9.81 m/s² (standard value on Earth).

Distance fallen (s):

s = (1/2) * g * t^2

s = (1/2) * 9.81 m/s² * (6 s)^2

s = (1/2) * 9.81 m/s² * 36 s²

s = 176.58 meters

So, the ball fell approximately 176.58 meters.

Final velocity (v):

v = u + (g * t)

v = 0 m/s + (9.81 m/s² * 6 s)

v = 58.86 m/s

The final velocity of the ball at the end of 6 seconds is approximately 58.86 m/s.
