The distance and displacement are both zero.
If you took a photo of Jamie before she started spinning, and another one
after she finished spinning, you couldn't tell the difference in the photos.
Her center of mass never moved, and all of her motion produced no change
in her 'position' (location).
The moon does not have an atmosphere because it is not a planet. It is just a big lump of rock that has a core. It was created from the Earth.
Explanation :
When a ball is tossed from an upper storey window off a building, the height of the object as a function of time is given by :

Here, u = 8 m/s
The ball strikes at an angle of 20 degrees below the horizontal. We need to find the time taken by the ball to reach a point 10 meters below the level of launching such that, h (t) = 10 m and a = g = 9.8



After solving the above equation, t = 0.855 seconds
So, the ball will take 0.855 seconds to reach a point 10 m below the level of launching. Hence, this is the required solution.
