The angular velocity of a circular saw blade increases from 0 rad/s to 120 rad/s in 5.4 s. The saw blade has a radius of 0.10 m and a mass of 0.125 kg. Treat the blade as a solid cylinder that rotates about an axis through its center. 20. What is the angular acceleration of the blade? 21. What is the tangential acceleration of a point on the edge of the blade? 22. What was the angular displacement of the blade during the 5.4 s? 23. What was the torque required to accelerate the blade? 24. How much work did the torque do on the blade during the 5.4 s?

A conducting rod is free to slide on two parallel conducting bars. A resistor is connected to the end of the bar. The conducting bar and the rod have negligible resistance. A constant magnetic field is directed perpendicularly into the page. The power dissipated in the resistor is 64 W. The constant speed of the rod is v=8.00 m/s. Find the magnitude of the applied force that is needed to move the rod with this constant velocity. Give your answer in N.
