### Mass & Mass & Pulley & Inclined Plane on TI-89: Video Transcript

This is a video from EveryStepPhysics.com

demonstrating how my programs work with the t i eighty nine titanium calculator

and other calculators in the t i system for physics and calculus problems

now we’re going to use the two masses on an inclined plane with a pulley and a rope

connected by ah to find mass m two I did another video on mass m one

but this one is going to be on mass m two to find it

ahh let’s get started again you press second alpha

and put the letters p h y s i c s in here

press alpha again and put the open and closed parenthesis

press enter and you’re into my menu we want to find mass

that’s what the problem asked for in your test

and so we need to go to mass here so we’ll scroll down to mass

there it is there we’ll press enter

and we’re into two masses on an inclined plane I ask you which one you want to find

m one which is on the plane or m two with the one hanging

so let’s find m two this time click down on that

press enter and mass one we’ll put in

you have to press alpha before you put anything into these entry

lines here I’m going to press alpha four

choose kilograms uhm for the angle I’m going to press

alpha nineteen and for the coefficient of static friction

I’m going to put point two three I always show you what you’ve entered

so you can change it if you want I say it’s ok

here’s the main formula that you derive these things from

and here’s m two the formula m two is m one times etcetera etcetera

and here’s your answer two kiligrams

two point one seven kilograms pretty neat huh
