projectile q (2 Viewers)

[anonymoushehe]

how would i do this q im kinda confused

 

[C2H6O]

Is this maths or physics

I'm guessing its maths cause g=10. Ah actually it doesn't really matter cause you get the same formula anyway

at 1 sec, the height of the projectile without gravity is , which you can get by integrating with g=0. WITH gravity, the height at 1 sec is which you get by integrating with g=10. Subtract the height with gravity at 1 sec from the height without gravity at 1 sec and the usinθ's cancel out nicely, leaving 5m.

Similarly at 2 seconds, you would do the same, giving the height without gravity at 2 as , and with gravity gives . subtracting these cancels the sines out nicely giving 20m.

Do the same for 3 sec and you should get 45m

If this is physics, the formula is just s=ut+1/2 at^2, and everything works out the same

Physics. But hsc physics doesn't approximate gravity to 10 m/s²

G=10 IN PHYSICS IS A WAR CRIME

just use Lagrangian

just use Lagrangian

the hell is that

integral of kinetic - potential energy wrt time, scalar application so u dont need vectors solves any mech q

This is reminiscent of "The Monkey and the Hunter" problem.
It goes like this (this story is not very politically correct, btw).
A cheeky monkey keeps stealing bananas from the farm.
The farmer gets a gun and waits for the monkey.
The farmer spots the monkey hanging from the top of a tree with his bananas.
The farmer aims at the monkey and shoots, but the monkey sees the gun flash and at the same moment he drops down out of the tree.
Will the bullet hit the monkey?

that was in my trials, zero clue wtf it meant

yes the bullet hits the monkey

Don't feel too bad about this.
In the sequel to this story, called "Planet of the Apes", the monkeys have the guns.
