Question

Identify the graph that displays the altitude of a skydiver as he is taken up in a plane and then jumps. I have eliminated "C"
@CGGURUMANJUNATH

Answer 1

Ok, so what is your initial guess?

Answer 2

I eliminated C so far..

Answer 3

As you are seeing, you y axis is representing altitude, and your x-axis time.

If we have a plane taking off, it is say at 0ft just before it leaves the ground say at time = 0
Then it is say at 100ft in a few seconds so let's call that t=2

Answer 4

So we have the plane rising in y as it rises in x, Altitude over Time.

Someone in the plane your saying is jumping out of the plane after getting to a certain height and is the dude we are measuring. So think of the guy as rising to a certain altitude from 0 then falling. Is this helping?

Answer 5

yes!

Answer 6

So what is your guess now?

Answer 7

Ma'am @lilia222 is it a physics Question ?

Answer 8

nope .. math

Answer 9

Ok then No Problem Ma'am

Answer 10

Matching a height/time graph to conceptual idea @goformit100, fun stuff =0)

Answer 11

Since he is rising, it is between "A" and "D"

Answer 12

But did he start when the plane was at a high altitude or on the ground?

Answer 13

Remember he is falling after jumping out of the plane =0)

Answer 14

Obviously skydriver will Jump from a height, not from the ground

Answer 15

Yes, but he rises from the ground when the plane takes off. Is my point here.

Answer 16

@lilia222 Let's look at answer D and explain to me why you think it is right or wrong.

Answer 17

it is between a and b ; the information proves it's b.

Answer 18

Where did the dude start if he was on the plane before it took off? On the ground right?

Answer 19

yes

Answer 20

I'm pretty sure he didn't get on the plane at 75,000ft... I assume he boarded while it was on the ground before take-off haha right?

Answer 21

right, haha

Answer 22

Ok so look at answer A.

Answer 23

When the graph starts, the guy is with the plane on the ground and rises with it as it gains altitude.

Answer 24

Then the graph levels off (supposedly for the skydiver before he jumps). Then he jumps and the graph falls... see?
