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: ->->->->->->->->->->->-> sion:
a = (.3 m/s)^2/.2m = .45 m/s^2 towards the axis
*
What is the magnitude and direction of the centripetal force required to keep it moving around this circle?
answer/question/discussion: ->->->->->->->->->->->-> sion:
I think it would just be .11kg * .45m/s^2 = .0495N
