Q:

A machine part rotates at an angular speed of 0.55 rad/s; its speed is then increased to 2.6 rad/s at an angular acceleration of 0.71 rad/s².

(a) Find the angle through which the part rotates before reaching this final speed.
1 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?
