Jules kicks a soccer ball off the ground and in the air with an initial velocity of 25 feet per second. Approximately what maximum height does the soccer ball reach?

Question

anonymous · Answer

i think the answer could be...
 (ignoring air resistance).
$$Maxheight = v^2f-v^2i \div 2a$$
So.
we can imagine the ball arrives into moment where the initial velocity becomes 0 and instantly starts to reach. So we get $$v^2f = 0$$

$$a= gravity $$
and is $$Maxheight= (0ft/s)^2-(25ft/s)^2 \div 2(32.1522ft/s^2)$$

and the answer is 
10,047ft

or at least i think it is
