Question

What is the common ratio between the successive height values of ball 1? Ball 2? Ball 3?
ball 1: (1,84)(2,29)(3,15)(4,7)(5,2)
ball 2: (1,84)(2,39)(3,19)(2,8)(3,4)
ball 3: (1,84)(2,59)(3,43)(4,36)(5,27)

Answer 1

I had to do an activity where I measured the height of a ball when I dropped it from 7 feet high

Answer 2

please someone help me :'(

Answer 3

Thinking...

Answer 4

okay thankyou soo much!

Answer 5

Aha.
Common ratio= h2/h1
where h1=any height.
h2=height of the next bounce.
Note that since this is an experiment, the common ratio will differ a little depending upon which two consecutive heights you choose.

Answer 6

so I just take the height divided by the next height
so 84/29 = 2.9

Answer 7

And I do that for each of the numbers?

Answer 8

wait what do I write then? Which one? cause they're all different

Answer 9

No, it's 29/84. & yea that's what I said. They will not match exactly because of experimental errors. But they should be close nevertheless.

Answer 10

so 29/84=0.34 so thats my answer?
or do I write all of the numbers I get?

Answer 11

Any one will do.

Answer 12

okay thankyou soo muchh!

Answer 13

yw. :)

Answer 14

can anyone answer this? If ball 1 were dropped from 2 feet higher, would the common ratio be different? Explain your answer.
*I think it would right?

Answer 15

Because its going to fall faster and bounce higher. So that would change it right?

Answer 16

If ball 1 were perfect it would have to be the same. But since it isn't, you'll get slight variations...

Answer 17

any doubts?

Answer 18

nope! thankyou so much! You really helped a lot!

Answer 19

Bye.
