Also in our textbook free fall is
-9.81 m/s^2
Alright in my class we are learning about free fall and crap.
I've wasted tons of time on thins one problem and it's now past midnight and I still haven't gotten it yet.
ok
Maria throws an apple vertically upward from a height of 1.3m with an initial velocity of +2.4m/s
If the apple is not caught, how long will the apple be in the air before it hits the ground?
Please show all of the steps you did because I got a completly wrong answer. The back of my book says that it's .82s
God Help...

if it is crap, and you are wasting your time, get out of the class, you have better things to do, like....
1) Go to the college bookstore, or BarnesNoble, and take a look at Schaums College Outline Series, College Physics. It will help you. And it is inexpensive.
2) the equation of motion is...
finalposition=intialposition+ vi*time + 1/2 g time^2
the final postition is zero, the initial postion is 1.3m .
g is -9.81m/s^2; vi is 2.4m/s
solve for time
0=1.3+2.4t - 4.9t^2
Use the quadratic equation.
