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
A = 30^2/20 = 45 cm/s^2
The magnitude of the acceleration is 45 cm/s^2. I don't know how to find the direction.
• What is the magnitude and direction of the centripetal force required to keep it moving around this circle?
answer/question/discussion: ->->->->->->->->->->->-> :
m = .110 kg
a = 45 cm/s^2
F = ma
F = .110 * .45
F = 0.0495 N
The magnitude of the force required to keep it moving around the circles is .0495 N.
