physics 101 chapter 9 question

An ploctric tumtable 0.780m in dameter is rotating about a fived inis with an inual angular volocity of 0.280rev/s. The anpular acceleraton is 0.855rev/s2. Part A Compute the angular volocity aher a fime d 0.202 s. Express your answer in revolutions per second. Correct Correct answor is shown. Your answer 0.44rev/s was either rounded diflerently or used a diterent number of sigrificant Figuresi than required for this part: Important: If you use this answer in later parts, use the full unrounded valoe in your calaulations. Part 8 Through how many revolutions has the blade turned in this time interva?? Express your answer in revolutions. x Incorrect; Try Again; One attempt remaining Part C What is the tangential speed of a poirt on the te of the blade at tirne t=0.202 s? Express your answer in meters per second. What is the tangential speed of a point on the tip of the blade at time t=0.202s ? Express your answer in meters per second. Part D What is the magnitude of the resultant acceleration of a point on the tip of the blade at time t=0.202s ? Express your answer in meters per second squared
