What is the acceleration of an iron sphere when it is lowered into the sea, what is its kinetic energy when it reaches the seafloor, and how long does its motion last? The depth of the sea is $m=100 \mathrm{~m}$. The diameter of the sphere is $d=0.20 \mathrm{~m}$. The specific gravity of the iron sphere is $\sigma=7.23$; the specific gravity of the seawater is $\sigma_{1}=1.05$.
