A steel ball of mass 110 grams moves with a speed of 30 cm / second around a circle of radius 20 cm.
• What are the magnitude and direction of the centripetal acceleration of the ball?
answer/question/discussion: ->->->->->->->->->->->-> :
Acceleration = 30cm/s ^2 / 20cm = 45 cm/s^2 (1m / 100cm) = .45m/s^2
The acceleration is going toward the center of the circle.

• What is the magnitude and direction of the centripetal force required to keep it moving around this circle?
answer/question/discussion: ->->->->->->->->->->->-> :
Force = .45m/s^2 * .11 kg = .0495 N
The force is pointing toward the center of the circle.
