Answer 1

Answer:

Angular acceleration is $3.33 rad/s^2$

Explanation:

Initial angular velocity $\omega_{1}=70 rpm$

Final angular velocity $\omega_{2}=130 rpm$

Time taken $\Delta t=18 s$

Angular acceleration is given by

$\alpha=\frac{d\omega}{dt} \\\alpha=\frac{130-70}{18} \\\alpha=3.33 rad/s^2$

Angular acceleration is $3.33 rad/s^2$
