its a formula u can derive using integration. i think u can also derive it using the suvat eqns asw but im unsure. that there is the formula for the maximum height approached by the proj motion.Ok now since Im done with projectile motion in mod 5 I havent come across this formula:

Is this from the old syllabus or something that pops in mod 5 later on? idk I searched the syllabus/ textbooks and couldnt find this so just making sure
thanks
is there a reason why not to memorise it? it doesnt seem that badits like a handy tool ig but you're better off not memorising it imo. maybe for practise you could derive it so you can see where it comes from
Im guessing you have done hsc physicsYou can't quote formulas not on the data sheet -> must prove them
yeah this is the reason. you can't use it straight up in the hsc. its only useful for multiple choice bc no working is needed (unlikely tho) and maybe its useful for quickly checking your answer for a longer question igYou can't quote formulas not on the data sheet -> must prove them
