plz view this

Answer 1

plz view 108 ??

Answer 2

First, what is relative motion?

Relative motion is motion of object 2 with respect to object 1

Relative velocity(v) of v2 with respect to v1 is
v = v2 - v1

Relative velocity(v) of v1 with respect to v2 is
v = v1 - v2

To make sure relative motion is uniform you need to make sure the v you are getting should be linearly dependent on t. i.e the t^2 terms of v2 and v1 should cancel out in v and v should be linearly dependent on t for uniform motion
t-->time

Now try :)

Answer 3

id nt understand plz can u solve 1st one as example

Answer 4

what is uniform motion??

Answer 5

moving with constant velocity

Answer 6

No ... not exactly!!

Answer 7

why?

Answer 8

uniform motion is something moving in a straight line at a consistent speed

Answer 9

r u talking about relative velocity??

Answer 10

yes ...

Answer 11

ok

Answer 12

plz go on

Answer 13

what is the condition for two particles to have same velocity with respect to each other?

Answer 14

if they are in opposite direction or same direction???

Answer 15

\[ \frac{d}{dt}x_1(t) - \frac{d}{dt}x_2(t) = k \]
K is constant!!
I think it should be like this!!

Answer 16

calculus???? i think it is the way

Answer 17

well ... if you try to see other way ... then it's easier if you can analize the given equation

Answer 18

derivative of distance is velocity

Answer 19

Wait ... i think i need to check the definition of uniform motion again!!

Answer 20

ok

Answer 21

http://en.wikipedia.org/wiki/Linear_motion
"uniform linear motion, with constant velocity or zero acceleration"

says \( \frac{d}{dt}x_1(t) - \frac{d}{dt}x_2(t) = k \) <---constant velocity

or \( \frac{d^2}{dt^2}x_1(t) - \frac{d^2}{dt^2}x_2(t) = 0 \) <--zero acceleration.

Now i think, you can find it!!

Answer 22

if you know your distance formula ... you don't need this stuff!!

Answer 23

we have find acceleration using derivative....

Answer 24

\[\sqrt{x2-x1 +y2-y1}\]

Answer 25

distance formula

Answer 26

when two particles have same velocity w.r.t each other??

then they have same acceleration ... Jeez ... what are you trying to do???


look for equations where they have same acceleration ...

Answer 27

derivative????

Answer 28

I think that @shivam_bhalla explained it pretty well :S
