The acceleration of gravity on Earth is about 9.8 m/s².
That means that if air resistance is neglected, a falling body
smoothly gains 9.8 m/s of downward speed each second.
If our intrepid chutist lightly stepped out of the plane or was
gently pushed, so that his initial downward speed was zero
and grew by 9.8 m/s every second, then it took him ...
(55) / (9.8) = 5.6 seconds
to reach that particular downward speed.

Answer:
5 solar days is 432,000 seconds
Explanation:
One solar day is the time the meridian of the Sun crosses passes through a specified place.
Due to the elliptical orbit of the Earth round the Sun, one average solar day on Earth is equivalent to 24 hours with some days longer and some days shorter each by a few minutes
Therefore, we have;
5 solar days = 5 × 24 hours × 60 minutes/hour × 60 seconds/minute = 432,000 seconds
5 solar days = 432,000 seconds
