The change in velocity (v₂ - v₁) is
<em> (-20) / (the object's mass)</em>.
Call it a crazy hunch, but I can't shake the feeling that there was more
to the question before the part you copied, that mentioned the object's
mass, and its velocity before this force came along.
1 m = 1 000 000 ym
converted other way we can say that:
1 ym =

m
Now, since we have ym^2 which is ym*ym which means:
1 ym^2 =

m
we have 1,5 ym^2 which means that answer is:
Answer:
diverging light rays of the bulb are collected by the reflector.
