1. My exam is tomorrow and I have this doubt. There are two formulas. One for range and one for TOF
Range = (u²sin2θ)/g
TOF = (2usinθ)/g

But I don't see these used in mark schemes but, when I use them I get the correct answer. Is it alright to use these formulas? While I gain full marks?

Unless specified to use a particular formula, then this should be fine. I'm assuming you've derived these from doing M1?

It was taught to me by my teacher, I've made another thread in the physics section, and my question was answered, so thanks for your time
