Question

A bird flies for 4 seconds with a velocity of |t-2|m/s in a straight line.It covers a distance of ____m and displacement of _____ m.Please help!

Answer 1

@mukushla remember...? :|
@Yahoo! @experimentX @Vaidehi09 @rdx

Answer 2

just intergrate the V

Answer 3

tell me what's ur answer first!

Answer 4

0

Answer 5

distance

Answer 6

displacement =0

Answer 7

that is obvious,distance?

Answer 8

is it 16 m

Answer 9

no

Answer 10

0..i think

Answer 11

noway

Answer 12

find the area under this curve for distance
|t-2|
the displacement is 2

Answer 13

no

Answer 15

we don't have to integrate

Answer 16

distance is 48m

Answer 17

oh ... sorry ... it's velocity.

Answer 18

no @Yahoo!

Answer 19

it is modulus...t-2

Answer 20

is it both 4m ??

Answer 22

history of this question XD

Answer 23

so it still remains that velocity = t-2 and speed = |t-2| ....

Answer 24

i though distance was function of time ...yahoo had asked similar Q ... just integrate that abs(t-2) from 0 to 4

Answer 25

it is the conclusion from the old history

Answer 26

but @experimentX but that would give answer as 0

Answer 27

well ... if your displacement was 2 to begin with ... depends on where you choose to measure it ... but wrt initial (it's zero) ... it were function of distance.

Answer 28

velocity = t-2 for t>= 2 And -t+2 for t<2

Answer 29

Yup......

Answer 30

@sauravshakya gud approach

Answer 31

The answer should be 8..i think

Answer 32

Oh.. its 4m

Answer 33

why don't you draw graphs!! ... this is just area of two triangles.
