Step-by-step explanation:
When the sequence of sides (shortest to longest, for example) remains the same (CW or CCW), then the number of reflections is even, possibly zero. The figure will have been <em>translated</em> if all of the corresponding sides retain their original direction, otherwise <em>rotation</em> is involved.
If the sequence is reversed, as in the upper right and lower left figures, then <em>reflection</em> is involved. The line of reflection will be the line through the midpoints of the segments connecting corresponding vertices.

SOLUTION
The object would hit the ground at the root of the equation, that is where h = 0
So we have
Solving the quadratic equation, we have
So we ignore -1 as time cannot be negative.
Hence the object hit the ground in 3 seconds
