A kid throws a ball vertically upward, and we measure that it reaches a

maximum height of $10$ m $.$ A professional pitcher tries the same thing, and the ball

leaves his hand at twice the speed of the kid's throw. How high does the ball go$?$

$($you may neglect the effect of air resistance$)$

$80$ m

None of these

$20$ m

$40$ m

$10$ m
