Pictures of the questions are attached below. For question 2, I totally cannot get any answer from the four choices after I substituted everything in the equation. For question 4, I used V^2= U^2 + 2AS, with U being zero, A being 9.8 and S being 2.0. I got C but the answer is D. Can someone explain it to me? For question 5: Firstly, why can't I calculate theta by directly using tan θ = 30/30 which makes θ=45°? And how do I get the answer? I have used (u sin θ)/9.8 = 1.2 but there are still two unknowns (u and θ). I can't find another equation to do simultaneous. Big thanks to anyone who can help me solve these. p/s: those are A-levels questions.
