Circular motion help!

  1. Oct 26, 2005 #1
    A 10 kg mass is traveling along a track at 3 m/sec. It enters a circular region of radius 3m.

    1. what is its speed at the bottom of the circular region?( I got 12 m/s)
    2. what is the normal force at the bottom?( I got 52 N)

    Right or wrong and if wrong whats the correct solutions/formulas to use.

    THANKYOU to whoever helps!

    Again, please describe the problem in more detail and provide your work, not just your answers.
