Question

Find the angular acceleration of a rotating body whose
angular speed changes from 25 rad/s to 50 rad/s in 10 mins​

Answer 1

$\large\rm { \:\:\:\:\:\:\:\:\:\:\:\:\:\:\: \alpha = \frac{\omega_{f} - \omega_{i}}{t}}$

$\large\rm { \ }$

$\large\rm { \:\:\:\:\:\:\:\:\:\:\:\:\:\:\: = \frac{ 50 \pi - 25 \pi }{10}}$

$\large\rm { \ }$

$\large\rm{ \:\:\:\:\:\:\:\:\:\:\:\:\:\:\: = 2.5 π \ rad/a^{2}}$
