Where g is the acceleration due to gravity which has a value of
substituting values
making the time taken the subject of the formula
The speed at which the pumpkin move horizontally can be represented mathematically as
substituting values
All stars appear to be stationary in the sky, comets, asteroids and meteors do not count as they are not stars unlike what has been seen on the earth
