Rotational speed equation physics
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 … WebThe formula v = r is true for a wheel spinning about a fixed axis, where v is speed of points on rim. A similar formulas v CM = r works for a wheel rolling on the ground. Two very …
