Question
Rotating Wheel A wheel rotates with a constant angular acceleration of 3.80 rad/s (A) If the angular speed of the wheel is 2.18 radjs at t,-o, through what angular displacement does the wheel rotate in 2.00 s B) Through how many revolutions has the wheel turned during this time Intervat (C) What is the angular speed of the wheel at t-2.00 s? (A) I the angular speed of the wheel is 2.18 radj's at t,-o, through what angular displacement does the wheel rotate in 2.00 s Conceptuallze Imagine a compact disc rotates with its anguler speed Increasing at a constant rate. You start your stopwatch when the disc is rotating t2.18 radys. This mental Image is a model for the mation of the wheel in this example. categorize The phrase "with constant angular acceleration" tells us to apply the rigid obiect under constant anguilar acceleration model to the wheel. Analyze From the rigid object under constant acceleration model, rearrange the equation so that it expresses the angular displacement of the wheel: A0-(2.18 rad(2.00 s1+(3.80 rad/(2.00 s)2 angular displacement at t-2.00 s (a B) Through how many revolutions has the wheel turned during this time Intervat Multiply the anguiar displacement found in part (A) by a conversion factor to find the (C) What is the angular speed of the wheel at t-2.00 s? ur-, + at . 2.18 rad/s + (3.80 rad/s202.00 s) Use the equation from the rigid object under constant angular acceleration model to find the angular speed at t- 2.00 s: Finaltze we could also obtain this result using equation w/-wi2 + 2at,-and the results of part (A). CTry ) Through what angle does the Wheel rotate between t-2.00 s and t 0.00 s?Explanation / Answer
A) 12.08
692.133
B) 1.9225
I hope you don't need the answer for the last one
