He will probably not succeed. Light does not travel as quickly through water than it does air, so the light will bend around the fish to make it look like it is in one place when really it is in another. I studied this a long time ago so I am kind of rusty on it, sorry. I really hope this helps. Have a great day!

No he won’t, because he is standing by a lake, not the pond the fish is in. Trick question!

Lilit [14]

Answer:

The nest must be about  4.15 meters above ground

Explanation:

Use the velocity equation under accelerated motion (acceleration of gravity ):

v_f=v_i+a\,*\,t

which for this case has initial velocity = 0 (falls from the nest), final velocity = 9 m/s, and a = 9.8 m/s^2, then we can find the time needed in air while falling to reach the required speed:

v_f=v_i+a\,*\,t\\9=0+9.8\,t\\t=\frac{9}{9.8} \, sec\\t \approx 0.92\,\, sec

We now use this time value to find the distance covered in free fall during 0.92 seconds:

d=\frac{1}{2} \,9.8 \,t^2=4.9\,(0.92)^2=4.147 \,meters\approx 4.15\,meters
