    Re: physics question

    A body moving in a circle, with radius R, with angular velocity \omega can be represented by the parametric equations x= R cos(\omega t), y= R sin(\omega t). Differentiating, the velocity vector is given by v_x= -\omega R sin(\omega t), v_y= \omega R cos(\omega t). Differentiating again, the accelertation is given by a_x= -\omega^2R R cos(\omega), v_y= -\omega^2 R sin(\omega t). And, of course, ma= F which you have from part a.

    A body orbiting another body in a circle has an acceleration towards the centre of its orbit given by a_n=\omega^2R This acceleration towards the centre is proportional to the force pulling it to the centre.

    Yes - that's correct. Be sure to note that your answer is in newtons.
