He<span> light </span>will<span> reflect off </span>the mirror<span> in a more orderly way than it reflects off </span>your<span> clothes. </span>We<span> call that specular </span>reflection<span>—it's </span>the<span> opposite to diffuse </span>reflection<span>. How </span>does the mirror <span>reflect light? </span>The<span> silver atoms behind </span>the<span> glass absorb </span>the <span>photons </span>of<span> incoming light energy and become excited.</span>
Density = mass / volume so mass = density x volume
2 litres = 2000cm^3
mass = 1.27 x 2000 = 2540g = 2.54 kg
The kinetic energy is the same as the potential energy of raising it 40cm (0.4m). That's mgh where m is mass of ball. Its then 3.924*m, whatever m is equal to in kg.
