this is a video on the ti 89 titanium program app
for physics with regards to physics equations
in this case we're going to tackle trajectories which are
in many tests there is a trajectory of a baseball hit
so let's get started to get to my main menu
you have to press second alpha and enter the letters p h y s i c s
then press alpha again to enter the open and closed parenthesis
press enter and you're into my menu my physics menu
there's many many things here you can scroll down to
atwood machine angular speed
acceleration angular acceleratio
centripetal acceleration et cetera
but we're going to do a baseball hit and we're going to enter out initial velocity
you have to press alpha before you enter anything in my entry lines
so let's just do alpha nine
meters per second initial velocity
I ask you if it's ok I say it's ok
so you can change it if you want ah you have these choices
time to height time to ground
time to maximum height we're going to scroll to maximum height right
here I show you the formula
all step by step show you the equations
and here's the four point one two eight four meters
for maximum height ah time to ground
there's one point eight three four nine seconds here's the formula again
minus g, minus nine point eight one meters per second squared
and here's time at maximum height
point nine one seven four three seconds here's the formula
et cetera all my programs are step by step
pretty neat huh? everystepphysics.com
check out my site enjoy my programs
and pass physics
