Question

a body is moving on a circular path of radius R and uniform angular speed. calculate magnitude of change in acceleration of particle after time interval of T/4

Open in App

Solution

Dear Student

In time T particle travel distance 2πR.
In time T/4 particle travel distance πR/2.

That is from initial position particle cover 1/4th of circle that is 90 degree.

ω = FINAL ANGLE - INITIAL ANGLE/ Time = π/2-0 /T/4=4π/T

Acceleration = ω²R= 16π²R/T²
