    9. A particle of mass 6 kg is initially at rest and is then acted upon by a force R = ai 10jN on a bearing of 300°.
    a Find the exact value of a.
    b Calculate the magnitude of R.
    c Work out the magnitude of the acceleration of the particle.
    d Find the time it takes for the particle to travel a distance of 640 m.

    Could you check what you have written as the force; it makes little sense.

    The question only says: a force R=(ai+10j)N on a bearing of 300*.
    Sorry think I have just repeated myself, I'm confused as well!

    What exaclty are you stuck on? For the first part, find the bearing in terms of a and equate it to 300

    I can read it now- it had some funny symboles in the original post.

    Sketch it and you know the angle between North and the force is 60 degrees to the left.

    I'm stuck on the same question but part a. I don't understand how to find a by equating the bearing to 300. I know it's 2 months after OP but if anyone could help that would be great
