Question

help me creating a word problem

Answer 1

the project i have to do is like this: http://mrskrummel.com/documents/tissueBoxProblem.pdf

Answer 2

my idea was to do something like
The velocity of a moving object can be described as

v(t)=t^2v(t)=t2

where t is in seconds and v is meters per second.. If the object starts at v=0 when t=0, how far has it traveled after 30 seconds?

Answer 3

how can i make that into a theme that i can decorate a tissue box about it?

Answer 4

help please

Answer 5

That's a good idea. You could make the theme speed and decorate it either with fast things, or as a fast thing itself... My first thought is to make a box into a drag-racer... Hopefully that helps in some way...

Answer 6

that's a good idea, but how do you think i can improve my problem to make it into like a story about the drag racer

Answer 7

wording the problem i mean

Answer 8

Well, you could ask how fast it's going when it reaches the end of a race, assuming a constant acceleration.

Answer 9

using a positional equation i suppose

Answer 10

a positional equation?

Answer 11

well a distance, or position, equation would be the integral of the velocity function, where velocity would be the integral of the acceleration

Answer 12

The velocity of a drag racer can be described as v(t)=t^2v(t)=t2 where t is in seconds and v is meters per second.. If the object starts at v=0 when t=0, how far has the drag racer traveled after 30 seconds? would this make sense

Answer 13

Didn't you say you needed to use integrals?

Answer 14

yeah

Answer 15

I'm not sure how to do that

Answer 16

ok, so you could tell them the rate of acceleration the car uses during its race, and explain how to find it's velocity at a given time with that information.

Answer 17

which would just be the integral of the acceleration.

Answer 18

okay thank you so much. how could i word that in the problem so it makes sense. sorry for asking so many questions

Answer 19

ok, um. something like: This car accelerates at 3m/s^2. if it starts a race at rest, how fast is it going 6 seconds later as it crosses the finish-line? The answer would be V(t)= the integral of 3t, which is equal to 1.5t^2+c, and C=0 because it starts at rest. so at time t=6 the answer is 54 m/s...

Answer 20

awesome thanks so much. i appreciate it

Answer 21

It is not a realistic equation, nor complex, but something similar should do.

Answer 22

No prob
