O RMplwww.webassign.net/web/Student/Assignment-Resic Search A circular saw blade 0.200 m in diameter starts from rest. In 7.00 s it accelerates with constant angular angular velocity of 120 rad/s. Find the angular acceleration and the angle through which the blade has tu rad/s rad 17 423.5 6. O 2/3 points | Previous Answers YF14 9.P.016. At t - o a grinding wheel has an angular velocity of 23.5 rad/s. It has a constant angular acceieration of 23 circuit breaker trips at t-1.90 s. From then on, it turns through 432 rad as it coasts to a stop at constant a acceleration. o) Through what total angle did the wheel turn between t-o and the time it stopped? 518 rad (b) At what time did it stop? 14.76 (c) What was its acceleration as it slowed down? 35.09 rad/s2 Submit Arawer Save Progress) Pradice Another 4/5 points I Previos Answers YF149 P026. At t 3.20 s a point on the rim of a 0.220-m-radius wheel has a tangential speed of 45.5 m/s as the wheel slows with a tangential acceleration of constant magnitude 12.5 m/s (a) Calculate the wheel's constant angular acceleration. -56 82 rad/s2 (b) Calculate the angular velocities at t . 3.20 s and t-o.
