Amachine part rotates at an angular speed of 0.07 rad/s; its speed is then increased to 3.4 rad/s at an angular acceleration of 0.50 rad/s2. (a) find the angle through which the part rotates before reaching this final speed. 11.5 correct: your answer is correct. rad (b) in general, if both the initial and final angular speed are doubled at the same angular acceleration, by what factor is the angular displacement changed? why?
