A coffee filter of mass 1.4 grams dropped from a height of 4 m reaches the ground with a speed of 0.9 m/s. How much kinetic ener

WITCHER [35]

Answer:

The kinetic energy gained by the air molecules is 0.054313 J.

Explanation:

Given that,

Mass of a coffee filter, m = 1.4 g

Height from which it is dropped, h = 4 m

Speed at ground, v = 0.9 m/s

Initially, the coffee filter has potential energy. It is given by :

$P=mgh\\\\P=1.4\times 10^{-3}\ kg\times 9.8\ m/s^2\times 4\ m\\\\P=0.05488\ J$

Finally, it will have kinetic energy. It is given by :

$E=\dfrac{1}{2}mv^2\\\\E=\dfrac{1}{2}\times 1.4\times 10^{-3}\times (0.9)^2\\\\E=0.000567\ J$

The kinetic energy Kair did the air molecules gain from the falling coffee filter is :

$E=0.000567-0.05488=0.054313\ J$

So, the kinetic energy Kair did the air molecules gain from the falling coffee filter is 0.054313 .
