Answer:
70.9pi rad/s
Explanation:
angle turned through = 16
angular acceleration = 22.6 rad/s2
angular speed = 10.2 rad/s
time = ?
angular acceleration = angular speed/time
time = 10.2/22.6
time = <u>0</u><u>.</u><u>4</u><u>5</u><u> </u><u>s</u><u>e</u><u>c</u><u>o</u><u>n</u><u>d</u><u>s</u>
<u>angular speed</u><u> </u><u>=</u><u> </u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u><u> </u><u>t</u><u>u</u><u>r</u><u>n</u><u>e</u><u>d</u><u> </u><u>t</u><u>h</u><u>r</u><u>o</u><u>u</u><u>g</u><u>h</u><u>/</u><u>t</u><u>i</u><u>m</u><u>e</u>
<u>angular speed</u><u> </u><u>=</u> (16 × 2pi)/0.45
= 70.9pi rad/s
