OCR M2 - Projectiles (pretty tough 11 marker) Watch
i) the maximum height of the missile above the level of the point of projection
ii) the distance of the missile from the point of projection at the instant when it is moving downwards at an angle of 10 degrees to the horizontal.
part ii is worth 11 marks, and iv no idea how to go about it. part i) = 22.5m if that helps you.
Solve for t, then calculate the distance. (I don't know if you're supposed to measure the distance as a straight line or just horizontal distance; in an exam I'd do both).
Thats all well and good but this is M2 and you're teaching him C3 / C4 methods.
OCR M2 assumes knowledge of C3/C4.
Interesting. Edexcel M2 doesn't.
Besides, who cares? Presumably the OP will have done C3 and C4 now so it doesn't matter where the relevant maths comes from.
