| 399431 | 2005-10-27 01:52:00 | Uh huh, thats what the tuition notes read. Tuition notes do not provide answers, just like your reply! A proper answer would be preferable. Ok here's another clue, the resultant velocity is given by v²=(dy/dt)² + (dx/dt)²=a²t²+u² Anymore and I'd be doing all the arithmetic for you, it's the reasoning that matters. I glossed over the integration by not mentioning the boundary conditions of x=o when t=0 |

| 399432 | 2005-10-27 02:26:00 | Won't the negative acceleration due to the Martian gravity ("-3.7 m/s/s") make a difference to the expected results, Terry? I didn't know the physics on Mars was that different. :D | Graham L (2) | ||

I didn't know the physics on Mars was that different. :D Yes Graham, I noticed that, but thought if I mentioned negative acceleration and the projectile taking off upwards, Veale would think I was boring again :) Most probably the surface of Mars is covered with Cavorite :thumbs: |

| 399435 | 2005-10-27 02:58:00 | If your doing NCEA you're allowed to use kinematic equations. Thats what I did, much easier than deriving them in exam conditions ;). | DangerousDave (697) | ||
| 399436 | 2005-10-27 03:37:00 | yeah for that first question i would of used those simple physics equations..... | Prescott (11) | ||
| 399437 | 2005-10-27 04:28:00 | Isaac Newton would have used the simple calculations he gave in the Philosophiae Naturalis Principia Mathematica . Even though he was one of the inventors of calculus . ;) That book is not very big, but it is very clearly written (in the English translation I read, anyway) . He was a very bright guy . |

| 399438 | 2005-10-28 02:40:00 | Nah, no worries . None of it made any sense to me Terry . Im not trying to learn it . It is a subject I want to pass and move on from . Been doing my job for 5 years and never encountered anything that resembles calculus . The 50+ year olds doing the same job have also never used it . My thinking, its a nothing subject unless ur interested in playing with numbers, pretty boring . Looks like I gonna have to fork out some dosh to pay someone over here to do it . Cheers anyhoo Veale |

| 399439 | 2005-10-28 03:23:00 | Fair enough, the questions suggested that a fair amount of calculus would have been covered. Not a topic of much use unless one is into engineering/electronic design work or similar. I have no idea what Maths 1b means, but the questions suggested to me something like 1st year at Uni, or at least 7th form, or year 13 whatever it is called. Cheers |

| 399440 | 2005-10-28 04:52:00 | Integration and differentiation is bloody useful in terms of physics. Anything in terms of electricity generally requires some level of differentiation or integration. I have a love/hate relationship with calculus... | DangerousDave (697) | ||
