Question

While preparing for breakfast, your mother throws the egg vertically upward creating a speed of 8.0 m/s at a height of 2 m. The mass of the egg is 1.5 g. Find its mechanical energy.

Answer 1

$E=KE+PE=\frac{mv^2}{2}+mgh=$

$=\frac{0.0015\cdot 8^2}{2}+0.0015\cdot9.8\cdot2=0.0774\ (J)=77.4\ (mJ)$ . Answer
