Speed and normal force for a 10kg mass in a 3m radius circular loop

[Cougar1112]

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 what's the correct solutions/formulas to use.

THANKYOU to whoever helps!
