Santa weighs 1781.8 n if the average chimney is 32 feet high how long (neglecting friction) does it take santa to get down the chimney? at what speed in m/s, km/hr, and mph, does santa hit the bottom?

On or near the surface of the Earth, under the influence of gravity
and no other forces, a body falls 32 feet in 1.41 seconds.

The speed upon impact inside the fireplace is 45.3 feet per second,
13.9 meters per second, 49.9 kilometers per hour, or 30.9 mph.

The weight of the body makes no difference.  If air resistance and other
sources of friction can be ignored, then a falling feather behaves the same
as a falling truck.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
