Maths method of PROJECTILE (1 Viewer)

[DaisyAnh]

for projectile questions, do you have to use the equations that is given to us?
CAN we use the method taught in maths?
i know for sure that you can't use physics method in maths but is the maths way permitted in physics exam?

Its one of those enigmatic questions >< ... every time I ask a teacher I get a different response, some say yes, some say no .. my tutor says yes, my teacher says no etc.. I for one prefer the maths ones but have made a point of learning the physics way (helps when maths was done last year I guess .. its sort of hard to juggle both methods) .. so soz for not offering a concise answer, Im hoping theres someone here who has asked a HSC marker

theres been another thread on this before, you CAN use maths
(its practically deriving the formulas anyway)

Read the syllabus. You are not supposed to.

i've been doing heaps of extension one papers, im worried i've forgotten how to do it the physics way. But how hard can substitution be, right?

Read the syllabus. You are not supposed to.

The Board Of studies clearly states that you can use 3 unit maths (i.e. calculus) to solve these problems. Mr Hong Kong found out by asking them directly - problem solved

"The general instruction given on the HSC Physics paper for answers
involving calculations is that all relevant working should be shown.
All legible responses following this instruction to obtain the correct
answer will be awarded full marks. While the HSC Physics course does not
require the use of calculus, responses that use it correctly will not lose
marks. Responses showing appropriate working, but an incorrect answer
gained through faulty arithmetic may still score some marks.
Please do not hesitate to contact me if you have any further enquiries.
