Question

A particle is performing cirulur motion its frequency of revolution changes from 120 rpm to 180 rpm in 10s the angular acceleration of the particle is​

Answer 1

Explanation:

π/10 is the answer.just use Newton's equation for kinematics converted for circular motion.

then 180 rpm means 180 rotations per minute which is equal to 3π/sec. As one rotation equal to 2π.

similarly 180rpm=4π/sec.

Then put the value and get the answer.
