Well here's your shmoop du jour brought to you by moving particles, sure [particles moving in a white space]

00:06

moving particles might not seem like such a big deal there are zillions of

00:09

particles bouncing around all over the place all the time but if all those

00:13

particles stopped moving we have a little thing called the heat death of [People screaming while surrounded by fire]

00:17

the universe yeah bet you think those moving particles are pretty cool now

00:21

well a particle is at rest at x equals 5 M at time T equals 0 s the particle

00:28

begins to move with an initial velocity of 2 meters a second and maintains an [equation of movement of particles]

00:34

acceleration of 1 meter per second squared well particle moves in a

00:37

straight line in the positive x-direction what is the location of the

00:42

particle at T 1 equals 6s and here's potential answers all right [muttering potential answers]

00:47

well there are ton of numbers in this question luckily we're

00:50

OK at math otherwise we might be in trouble now in order to solve this [Boy at his desk doing math homework]

00:54

problem we need to use our equation of motion which looks a little something

00:57

like this in this equation X represents distance V represents velocity A is [physics equation for motion]

01:04

acceleration and T is time well X sub 0 is the starting distance and V sub 0 is the

01:10

starting velocity well let's do a roll call to make sure we've got [Roll Call check list on a clipboard]

01:15

everything we need Kizer well do we have a starting distance yep that's 5 meters

01:20

how about a starting velocity that's 2 meters a second acceleration you hear

01:25

well 1 meter per second squared got it and last but not least time err that'd be

01:30

six seconds pop all that into our equation and what pops out is 35 meters

01:35

so option C is the answer these equations are going to come in handy so

01:39

[Boy hitting his laptop in frustration] we better start memorizing them after all the heat death of the universe isn't

01:43

expected to occur for at least 10 to the hundredth years so we can't rely on that [Earth covered by fire]

01:48

to avoid the AP physics exam.
