An object is spinning with an initial angular velocity of 19.9 rad/s. over time of 1.37 s the object increases its angular velocity to 37.7 rad/s. What angular acceleration did the object undergo during that time?



Answer :

The object underwent an angular acceleration of approximately 13 rad/s².

initial angular velocity = 19.9 rad/s

over a time of 1.37s, angular velocity increases

new angular velocity = 37.7 rad/s

change = 37.7 rad/s - 19.9 rad/s

change = 17.8 rad/s

17.8 rad/s / 1.37s = 12.9927 radians

or approximately 13 radians per second acceleration

acceleration = 13 rad/s²
