Question

If you go from 0 m/s to 50m/s in 5 seconds what is the distance you have traveled PLEASE HELP I just need some clarification

Answer 1

would the answer be 150 meter as each seconds she goes an average of 10m/s faster

Answer 2

If you're learning kinematics equation you would use (xf - xi) = vit + (1/2)at^2
We know what our initial velocity is = 0m/s
we know what our final veloctiy is =50m/s
we know what time it takes = 5s
we need to find acceleration.

acceleration can be found by (vf - vi) / t

Answer 3

with all the variables known except for x, you can now find the distance

Answer 4

THANK YOU

Answer 5

WAIT what does vit stand for

Answer 6

intial velocity * time?

Answer 7

yea

Answer 8

thanks for the clarification

Answer 9

np

Answer 10

:)

Answer 11

you a life saver

Answer 12

would the answer be 2.5 or did i mess up

Answer 13

oh shoot i messed up

Answer 14

i haven't done the calculated haha.

Answer 15

wait so if x equals the distance traveled.........

Answer 16

yeah, you know that initial distance is 0m so you're looking for the final distance

Answer 17

wait so i got x=2.5secs

Answer 18

(x - 0) = 0m/s ( 5seconds) + 1/2 (10m/s^2) (5seconds) ^2

Answer 19

and x = displacement

Answer 20

i still got x=2.5 secs

Answer 21

are the seconds supposed to cancel out?

Answer 22

AHHH

Answer 23

you just plug it in lol

Answer 24

what are you stuck on?

Answer 25

i think i am simplifying wrong

Answer 26

you don't need to simplify anything hahahaha

Answer 27

I don't?

Answer 28

write down the given for me

Answer 29

5 seconds is the given right?

Answer 30

yea, what else

Answer 31

the velocity

Answer 32

you also have one more

Answer 33

its kinda hidden, but your initial distance is 0m

Answer 34

acceleration?

Answer 35

oh yeah

Answer 36

okay so you have
t=5s
vi = 0m/s
vf = 50m/s
xi = 0m

Answer 37

you're using this kinematic equation (xf - xi) = vit + 1/2at^2

Answer 38

what are you missing?

Answer 39

xf?

Answer 40

and?

Answer 41

vf?

Answer 42

acceleration, but you can find accerlation with vf - vi / t

Answer 43

and a = 10m/s^2

so now all you have left is xf

Answer 44

(xf - 0 ) = (0) + 1/2 (10) (5) ^2

Answer 45

is it 125!

Answer 46

yea

Answer 47

YESSSSSSSSS I DID IT THANK YOU

Answer 48

what grade are you in

Answer 49

i think i misinterpreted t^2 as seconds squared

Answer 50

I am in 9th

Answer 51

i know its sad

Answer 52

did you guys learn kinematic equation yet?

Answer 53

Its a little sad I got messed up by seconds squared

Answer 54

no

Answer 55

how does your teacher go about doing this question

Answer 56

Sasha drives her hovercraft from 0m/s to 50 m/s in 5 sec, how far does she go

Answer 57

thats the orginal question

Answer 58

how does your teacher solve it?

Answer 59

its hw we havent gone over it yet

Answer 60

surprise your teacher!!!! lol

Answer 61

thanks

Answer 62

you have the patience of a sain

Answer 63

sorry i meant patience of a saint

Answer 64

thanks I owe you

Answer 65

study hard!!! don't slack

Answer 66

Got it! Good luck in whatever you study
