A particle is projected at an angle of 45[FONT=DejaVu Sans, sans-serif]° and a velocity of 15ms^-1. Without neglecting air resistance (13.5[/FONT][FONT=DejaVu Sans, sans-serif]Ω), and taking g as 9.8ms^-2
[/FONT]

a) DERIVE THE EQUATION FOR THE PARTICLE FOR (I) HORIZONTAL AND (II) VERTICAL DISPLACEMENT (IN EXACT FORM)

b) FIND THE TIME TAKEN TO REACH THE GROUND.

will you actually give me $100 if i scan up the worked solution??

 

[Aerath]

Don't count on it.

 

[conics2008]

which direction is the air resistance ?

 

[lyounamu]

which direction is the air resistance ?

It's always against the projectile's movement, isn't it?

 

[proringz]

Since when was air resistance measured in ohms

 

[independantz]

Since when was air resistance measured in ohms

Rofl.

It's always against the projectile's movement, isn't it?

Yeah it is.

 

[proringz]

Since air resistance is not measured in ohms (or any units for that matter), the question is unanswerable and so, that is my answer. Now gimme my $100

 

[E-Dog]

It's always against the projectile's movement, isn't it?

bingo

 

[Js^-1]

Gimme the current and I'll work out the voltage

Again, this question is an epic fail.

 

[friction]

13.5 ohms is the stuff up. Air resistance as always will be preportional to velocity or velocity squared or something tell me what that is and ill find u the answer. Or i can assume one of them and give u the answer. Even ifu tell me what velocity the air resistance is at that i will give u the answer. If u give me $100. Its Just Ext 2 not too hard.

 

[Aerath]

What would air resistance be measured in?

 

[conics2008]

what if air resistance is with the velocity projected ??

there are alot of cases ??

play the game "tanks" lol.. im thinkin about that...

 

[kaz1]

What would air resistance be measured in?

Wind is sort of the same as air resistance so I think it might be m/s.

guys - i posted this on saturday night (sunday morning?) at 3am while i was embarrassingly drunk. air resistance is ridiculously difficult to measure, relies on countless variables, and is definatly not measured in ohms.

dont answer it - actually do some proper study. lol.

 

[tacogym27101990]

why were you on bored of studies posting shitty maths questions when you were drunk..
heaps sick...

and air resistance isn't that difficult

how the fuck could u have typed that up (without spelling mistakes) if u were that drunk?

 

[lost1]

I'm guessing air resistance would be measured in Newtons (or the likes) since its a resistive 'force'

 

[jasonml]

It took me like two hours, and i was copying out of a textbook lolol (though i obviously added the air res bit)
