Webr = 12 cm. First we calculate the period. Since 45 rpm = 0.75 revolutions/second. Thus the period of rotation is 1.33 seconds. Thus the speed will be. v= 2πr/T = 2π (10 cm )/ 1.33 … WebNov 30, 2004 · It depends on the amount of friction of course, but most likely yes. Friction losses for rolling are generally much less than for sliding. Here's something else to think about: Without friction, the marble wouldn't roll. Static friction is required to get the marble rolling. Nov 28, 2004.
