well its basically the same stuff anyway, but remember that certain physics equations that are on the formula sheet are in the syllabus, so u would probably be expected to show that u know how to do the projectile motion stuff using those.

Yeh it's possible, and you can use it. The physics formula's are the projectile motion ones, but simplified. ie u = vsin@ etc.
????? is that a yes?? so it ok just make sure you know the physic formula also????

lol
maths came from physics
hence maths projectiles is the same as physics projectiles

for example finidng the maximum height in physics projectiles, u let Vy = 0
now if we look at this practically, the object will never actually stop in the air for a time interval, only for an instant. it will go up up up up then down down down, at an instant changing direction. now, how do we take a measurement at a point ( since we don;t have two points to have a time interval between them)...we use calculus and take a very small change in the time (like quantum physics)... except in regards to quantum physics, hiesenberg's states that any observation made at an instant, will be different to what is actually happening.

therefore calculus is stupid... :D (for maths in theory, (which is physics) it is fine , but using it to transcribe physics is BAD)

end of rant.

my teacher told me you have to use the formulas from the formula sheet (which would mean to cant go integrating and stuff)
