Radius of the blade = 4 - in. = 0.33 ft. Blade spins at 5,000 rpm. Explanation: The formula we are using: Angular speed = 2mm Put the values into the formula: = 2 x (5,000) = 10,000 rad/min. Answer. Step 2 b). Explanation: The formula is: w x r 2n = x 0.33 = 60 10,000 60 = 10 33 33 100 = 55.1 ft. /s. Answer. Answer The answer is: a). 1000 rad/min. b). 55.1 ft./s. 11.
