For the projectile question (14aii), I equated x = vtcos(theta) and x = (v^2sin2(theta))/g, as they both equal x.

Then, simplifying on both sides, I get theta = sin-1 (1/√3)

hey guys if I got 59/70 is that a band 5? I also wrote root(11/4) for the n value idk if they'll take a mark off for not simplifying to root(11) / 2

Hey guys, for the projectile motion question, are we supposed to write pi/6 or 5pi/6 if it asks for the angle that the particle makes with the horizontal?
