In 1932, Albert Dremel of Racine, Wisconsin, created his rotary tool that has come to be known as a dremel. Suppose a dremel

In 1932, Albert Dremel of Racine, Wisconsin, created his rotary tool that has come to be known as a dremel. Suppose a dremel starts from rest and achieves an operating speed of 35,000 rev/min. If it requires 1.20 s for the tool to reach operating speed and it is held at that speed for 49.0 s, how many revolutions has the bit made? What is the average angular acceleration ,2 for the start-up period? 0 = 3,z rev || 1,z Suppose it requires another 8.30 s for the tool to return to rest. What is the average angular acceleration a3,z for the slow-down period? How many revolutions tot does the tool complete from start to finish? rad/s = Orot rad/s = rev
