A small air bubble separated from the the bottom of the pool
filled with water, and reached the surface in T = 5s later.
The depth of the pool is d = 1m. Estimate how much time τ
did it take for the bubble to acclerate to the speed v= 1cm/s.
I am confused. I tried to apply the formula from the textbook
a = d/2T² , and then τ = v/a = 2vT²/d and get = 50 ms, but
it's nowhere near the answer, not even close. Please help.
