    Answer:

    Explanation:

    Given

    Weight of person W=652\ N

    At highest point Magnitude of the normal force F=585\ N

    net force at highest point

    F_{net}=W+F_c

    where F_c= centripetal force

    F_c=\dfrac{mv^2}{r}

    F_{net}=F_{n}= Normal Force

    585=652+F_c

    F_c=-67\ N

    Negative sign shows force is in upward direction

    At bottom point centripetal force is towards the bottom

    F_n=F_c+W

    F_n=652+67

    F_n=719\ N
