The blades on the mower turn 60 times per second. 3b) What is the magnitude of the force needed to hold the outer 2 cm of the blade to the inner portion of the blade? The outer edge of the blade is 21cm from the center of the blade, and the mass of the outer portion is 7.5 g. Even though the blade is 21cm long, the last 2cm should be treated as if they were at a point 20cm from the center of rotation.
