Answer to Question #60254 in Mechanics | Relativity for tanvi dalsania

Question

A particle is revolving in a circular path of radius 25 m with constant angular speed 12 rev/min. Then the angular acceleration of particle is?
ans is zero

Answer 1

We can write the equation of angular speed: ω(t)=12 rev/min. Angular acceleration is derivative of angular speed with respect to time: ε(t)=(ω(t))'=12'=0 rev/((min⁡ )^2 ).
Answer: 0 rev/min2.
