The diagram represents Earth in its orbit around the Sun and the Moon (M) in different positions in its orbit around Earth. Lett
ers A through D represent four positions of Earth in its orbit. Earth is closest to the Sun near position D and farthest from the Sun near position B. Identify the lettered position of Earth and the Moon when this full moon phase can be observed, and state the name of the eclipse that could occur at this position.

Explanation:
Given
initial speed(u)=3 m/s
mass of each ball is m
Let the cue ball is moving in x direction initially
In elastic collision Energy and momentum is conserved
Let u be the initial velocity and be the final velocity of 8 ball and cue ball respectively
The angle after which cue ball is deflected is given by
Conserving momentum in x direction
Along Y axis
substitute the value of
we get
