FORMULAS: 8 s = Or S= - 2 v= 360 v = rw W 39. The wheel of a machine rotates at the rate of 300 rpm. If the diameter of the wheel is 80 cm, what is the angular velocity (in radians per second) and linear velocity (in cm per second) of a point on the wheel? 2=80 (240 Bd 40. Convert your linear velocity from above to miles per hour. (Use 1 inch = 2.54 cm)
