    What did everyone get for the force F2 on the vector question?
    2.5 i + 2.5 j

    Connected Particles
    T=11.76
    Resultant force = 16.6 bearing 45 degrees

    For the connected particles i got the tension but 16.6 N for the force exerted on the pulley in direction 225 degrees i think

    Anyone agree or disagree with these answers?
    Vectors
    1a) 104 degrees
    C) 640i+640j

    Pan on cable
    2a) 20.6N
    B) 15.5N

    Particle into a wall
    3) 1.4Ns

    Speed-time graph
    8.75s

    Moments
    M=42
    D=1.2

    Slope question
    Coefficient = 0.73

    Vectors (again)
    F2= 2.5i+2.5j
    Speed=13

    Connected Particles
    T=11.76
    Resultant force = 16.6 bearing 45 degrees

    Flip! I didn't give a bearing for the last question, but got 16.6. And I **cked up the second part of the vt graph question.
    Otherwise, my answers look pretty similar to yours

    I got root5 over 2, how the hell were you supposed to do that question?? 😂
    I think you have to do parallel vectors, there were so many vector question😂

    Yeh I got all of those answers apart from the Impulse answer with the wall, I got 3Ns, probs got it wrong

    These answers are from several people agreeing on them from my year group, should be mostly right

    Find the angles using the vectors they gave you, make a triangle of forces, use sine rule to find the magnitude of F2.

    Since F2 is parallel to vector (i + j), the lengths would be equal. Then use sine rule again to find the length (which I found to be 2.5)

    Does anyone remember what they did for the pan question?
    for part a) I used T- particle x g = particles x a
    I forgot what i got as an answer though:\
    basically I used the values for the whole system instead of just one particle.
    Is that right???

    2.5i + 2.5j and the speed was 13 m/s

    So obvious edexcel trying to trip us up at every corner. First question a vector one! Impulse question was a nightmare, I ended up with 3 Ns.

    Moments question: d = 6/5, M=42
    First vector one: 104 degrees, 640i + 640j
    Lift question: T=20 something I think, R on pan = 15N
    Kinematics graph: T=8.75 (or there abouts)
    Statics problem: friction coefficient = 0.73
    Second vectors: 2.5i + 2.5j and 13m/s
    Dynamics pulley: T=11.something or (6g)/5 and resultant = 2Tcos45, at 45 degrees from the horizontal

    All those answers from bcmh are correct apart from the Impulse, it was 3Ns
