1. The problem statement, all variables and given/known data An electric turntable 0.710 m in diameter is rotating about a fixed axis with an initial angular velocity of 0.230 rev/s. The angular acceleration is 0.887 rev/s^2. A. Compute the angular velocity after a time of 0.192 s. B. Through how many revolutions has the blade turned in this time interval? C. What is the tangential speed of a point on the tip of the blade at time t = 0.192 s? D. What is the magnitude of the resultant acceleration of a point on the tip of the blade at time t = 0.192 s? 2. Relevant equations Any rotational kinematic. Conversions to radians/revolutions 3. The attempt at a solution A.) I took the angular velocity 0.230 and multiplied it by 2pi which equals 1.445 rad/s. I then plugged it into a kinematic equation, 1.445+(0.887*0.230)^2 = 2.56 rad/s = .400 rad/s. This is right. B.) The I used the distance rotational kinematic equation, 1.445 * 0.230 +.5(0.887)(0.230)^2 = 0.3558 rad. = 0.57 rev. This is wrong. Need help. C) To to find the tangential speed, I did 0.710 m * 2.56 rad/s = 1.82. This is wrong. Need help. D) Need help. Thanks.
