Answer to Question #167781 in Mechanics | Relativity for Lilian

Question

An egg rolls off the edge of a table 1.2-meter-high and strikes the floor at a

point 2 meter horizontally from the edge of the table.

Answer 1

Answer

Using

For time $t=\sqrt{\frac{2h}{g}}\\=\sqrt{\frac{2\times1.2}{10}}\\=0.49sec$

Now speed of rolls is given by

$v=\frac{distance}{time}=\frac{2}{0.49}=4.08m/s$
