An object is projected downwards with initial velocity V0. The air resistance at speed v has magnitude mkv, where k is a positive constant. Take downwards as the positive





direction. 􏰃 (a) Show that t = 1 loge

k



􏰄

g−kV0 . g−kv





(b) Hence show that v = g (1 − e−kt) + V0 e−kt, and that the terminal velocity is g . k􏰀􏰁k





(c) Integrate again to show that x = gt+ kV0−g 1−e−kt . k k2





(d) Suppose that the terminal velocity of this object is 20 m/s, and that g = 10 m/s2. The object is thrown vertically downwards from a lookout at the top of a cliff at precisely the terminal velocity. At the same instant, a similar object is dropped from the same height. Show that the distance between the two falling objects after t seconds is

2
40(1 − e− 1 t) metres, and hence state the limiting distance between them.


uh copy paste didnt work but what does limiting distance mean? like is it max distance or what? that doesnt sound right but idk what it means?

limiting distance is what it approaches as time approaches infinity iirc

you’ll be fine trust at least your chem teacher won’t be there

carrots. the principal is a sex offender.

bro what

ok but what does the term 'limiting distance' mean?

 

[nsw..wollongong]

bro what

mf apparently didn't have enough funds to take it to court so he tries to keep it on the low

wtaf how can someone remain principal and be a sex offender

ASK HIM. IDFK. IF I DONT WALK HOME TMR WITH A DRUG INFESTED BAG ILL BE SHOCKED, EVERYONE THERE EITHER SELLS COKE OR TAKES IT

 

[nsw..wollongong]

nah im jk its not that bad

 

[its_ace21]

nah im jk its not that bad

u cow this is why i have trust issues

 

[carrotsss]

ok but what does the term 'limiting distance' mean?

the distance as time approaches infinity

so for this q, as t->∞, e^-t->0, so the limiting distance is 40

SURELY IT CANT BE THAT BAD OF A SCHOOL LIKE I KNOW ITS WOLLONGONG BUT

fuck off that's what my sister calls me

yes but what the fuck does LIMITING DISTANCE MEAN
IS IS WHEN THE PARTICLES ARE THE CLOSEST TOGETHER
UR JUST TELLING ME HOW TO FIND IT

 

[nsw..wollongong]

its not Wollongong man that was my previous school

 

[synthesisFR]

I thought its like
since one is dropped the terminal
then one is dropped from rest
as t goes to infiinity they both travel at terminal velcoity
then they are a constant distance between each other which is the distance that is travelled as the second particle accelerates to terminal
correct?

 

[carrotsss]

yes but what the fuck does LIMITING DISTANCE MEAN
IS IS WHEN THE PARTICLES ARE THE CLOSEST TOGETHER
UR JUST TELLING ME HOW TO FIND IT

I JUST SAID ITS THE LIMIT OF THE DISTANCE LIKE WHAT THE DISTANCE APPROACHES BUT NEVER REACHES

 

[carrotsss]

its not Wollongong man that was my previous school

damn now ur username is just a lie

 

[nsw..wollongong]

damn now ur username is just a lie

I'm a fraud i know

 

[nsw..wollongong]

We know.

get ur smoking catass outta here
