Yeah, this.
You are ing dumb if you're doing this stuff at school with a text book and can't work it out. Physics is one of the easiest kinds of maths, at least at this level. |
ok genius i gave you all the equations and 50 % of the question.. figure it out lol
I suggest you eat some meat before you attempt it though. |

whats dumber is if you say its so easy and then can't solve it. |

Apparently you can't read either. It's been the better part of a decade since I did physics at school, I'm about as likely to remember that as I am to remember this thread in 10 years time. |

apparently you can't read either.. i gave you all the equations and a diagram. This was an exam question, obviously its going to be trickier then anything in the text book.
Anyways.. sorry im so stupid i can't solve a physics question lol. |

well, i wouldn't go that far. Nrg2Nfinit is pretty damned smart. |

see look what happend when you stopped eating meat. You started to lose your memory. You're slowly turning into a lemur.
edit: hold on to your earlobes. |

here i posted what i solved for
x=xo + vot (no acceleration in x component)
1)y=yo+vot +1/2 at^2
2)v=vo+at (you can use this for y component)
3)v^2=vo^2+ 2ay (you can use this for y component as well)
so for the first part i got the angle by using tvocos@=x
since i have x t and v i can solve for @ which gives 31 degrees.
From there i found my y componet by first solving for distance to zero velocity which gave 15.5 meters (v2=v02+2ay) where v=0 a -9.81.
I also solved for how much time that took using v=vo+at which gave me 1.78 seconds. I can subtract this from 5 to give me the remaining time that it will take to hit the ground from maximum height (zero velocity) 3.21.
I can use y=yo + 1/2at2 to solve for the distance to hit the ground from zero velocity. I subtract this number (50.7) from 15.5 and i get the height of the building to be 35.2.
This is all for the first stone (black) now all i know for the second stone (red) is that it lands 2 seconds after the first stone and it has the same velocity (35m/s).
Good luck |
if it has the same velocity it has to have a more acute angle... your longest time of flight will be when theta = pi/4 rad |

Me not eat meat? :stongue:
I despise fruit and vegetables. I could probably count the pieces of fruit I've eaten this year on one hand. |

i would think a larger angle would give more flight time at the same velocity |
