Question

Help with Physics?

Answer 1

A person standing on the escalator takes time t1 to reach at the top of a tower when the escalator is moving. He takes time t2 to reach the top of the tower when the escalator is standing. How long will he take if he walks up a moving escalator?

Answer 2

Why not post it in Physics group?

Answer 3

cause there arent many people there...

Answer 4

Of course there are.

Answer 5

ok :)

Answer 6

Thanks for understanding :)

Answer 7

this question was initially asked by me but @camerondoherty helped me to ask it in a other way

Answer 8

can we take distance as d

Answer 9

there is no distance its all time

Answer 10

well distance too but theyre asking for time lol

Answer 11

speed = distance / time
Do u agree

Answer 12

tru

Answer 13

yes the same thing i was saying @camerondoherty u really are not god at physics lol

Answer 14

who?

Answer 15

me XD

Answer 16

i was just joking i am also not too good

Answer 17

so when the elevator is moving up
s = d/t1

Answer 18

yes i tried the same

Answer 19

but i was"nt able to come to a solution

Answer 20

so when the person going up
s of person = s/t2

wait @kanwal32 i will tell

Answer 21

He walks up a moving elevator means both the person and elevator are moving

Answer 22

means both have speeds

Answer 23

yes

Answer 24

ill leave this 2 u guyz..

Answer 25

then simply add the speeds

Answer 26

S + Sp = d/{(t1 + t2)/(t1.t2)}

Answer 27

yeah (relative velocity)

Answer 28

t = {(t1 + t2)/(t1.t2)}
Question over

Answer 29

got it thnx @No.name

Answer 30

no problem

Answer 31

Physics is really great when you enjoy it

Answer 32

yeah i love physics its better than any subject

Answer 33
