Question 1192812
.
A ball is thrown from 1 m above ground level. It's velocity is v(t) = 29.4-9.8t ms^-1. 

a. Find the displacement function s(t) (I found this: 29.4-4.9t^2+1

b. Find the maximum height reached by the ball (need help in this).

Consider these lessons as your textbook, &nbsp;handbook, &nbsp;tutorials and &nbsp;(free of charge) &nbsp;home teacher.
Read them attentively and learn on &nbsp;HOW &nbsp;TO &nbsp;solve this type of problems once and for all.


Start reading from the very first lesson in this list and &nbsp;LEARN &nbsp;FROM &nbsp;THERE &nbsp;on how to write &nbsp;CORRECTLY 

the basic equation for the height, &nbsp;because your equation in your post is written &nbsp;INCORRECTLY.



You will know the subject, only when you learn the meaning of each term in the height equation.


Very first lesson in the list will teach you about it.
