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: ->->->->->->->->->->->-> :
a=v^2/r=.3m/s^2/.2m=0.45m/s^2
direction is 90 deg (at a right angle from the current velocity)

• What is the magnitude and direction of the centripetal force required to keep it moving around this circle?
answer/question/discussion: ->->->->->->->->->->->-> :
f=ma=0.45m/s^2*.11kg=0.0495N
direction is 90 deg (at a right angle from the current velocity)
