Motion

A small steel ball is dropped from a height of \(1.5 \mathrm{~m}\) into a glycerine jar. The ball reaches the bottom of the jar \(1.5 \mathrm{~s}\) after it was dropped. If the retardation is \(2.66 \mathrm{~m} / \mathrm{s}^2\), the height of the glycerine in the jar is about (acceleration due to gravity \(g=9.8 \mathrm{~m} / \mathrm{s}^2\) )
