Question

Be sure to account for both drop and rebound distances.

Answer 1

@tHe_FiZiCx99 may help you. :}

Answer 2

you would take 10 feet and multiply it by 2/5 or 40%. to get the height after the first bounce. then keep doing this to get to the 5th

Answer 3

i would draw a fbd like this and include each distance dropped and rebounded. then take the sum of them all

Answer 4

So if I multiply the first one (10x 2.5= 25) Then the second one I multiply 2.5 with 20? or what?

Answer 5

no its 2/5 or 40% not 2.5

Answer 6

Step 1: 10 x 2/5= 10 2/5
Step 2: then??

Answer 7

Do I multiply 10 2/5 x 2/5 to get my second?

Answer 8

no. 10 *2/5 is 4 so it would bounce the second time 6

Answer 9

I'm confused now

Answer 10

you lose 40% of your height on the second bounce. you are losing kinetic energy as the ball bounces. therefore your potential energy is lower the second time. making the second height lower.

Answer 11

So I multiply 6 x 2/5?

Then loose 40% from 6?

which i will get 2 for the third bounce?

Answer 12

@lonnie455rich ?

Answer 13

2.4 if you round. you might not get the correct fraction

Answer 14

1 bounce is 10
2nd bounce is 6
3rd bounce is 2.4
4th bounce: I loose 40% out of 2.4?

Answer 15

yes. and remember in the sum to consider the bounce and the drop

Answer 16

4th bounce is: 0.06. ?

Please bare with me I'm new to this.

Answer 17

i got .96. and , your fine

Answer 18

Wait how did you get that? I devided 2.4 by 40%

Answer 19

you multiply by .4

Answer 20

Oh i see. so my fifth bounce would be .96 x .4 = .384?

Answer 21

yes

Answer 22

I got my final answer 20 112/125. which isn't part of my answers

Answer 23

you didnt add the drops

Answer 24

the drops as in .4 ?

Answer 25

no the ball falls each step as well as bounces

Answer 26

What are the balls drops?

Answer 27

same as the bounces

Answer 28

I got B. Is that correct?

Answer 29
