Answer:
The lights bounces from the object behind which hit one's eyes. The glass is transparent because it does not absorb any radiation
Ok the velocity of an object in free fall is given by the equation :
v=v0-gt, where v0 is the original velocity, g is the gravitational constant (9.8 m/s^2) and t is the time.
so, we substitute values into this equation. v=35.8-9.8*2.5; v=11.3 m/s
<span>The formula for average velocity is: (final distance - initial distance9 / (final time - inital time). Using that, the anwer will be:
(3.13 - 13.4)m / (4.6 - 1.72)s = - 3.57 m/s.
According to these results, if we assume positive numbers are right, the particle was moving left.</span>
