Question

A wheel starting from rest, rotates with 5 rad/s2 angular acceleration along its axis. After 2 s of motion, the magnitude of radial and tangential component of acceleration of the particle at a distance 2 cm from the axis are ________ and ________ cm s2.
  1. 200,5
  2. 50,10
  3. 100,5
  4. 200,10


Solution

The correct option is D 200,10
Given, α=5 rad/s2,t=2 s and
r=2 cm

Now to find the radial and tangential component of the acceleration

at=rα=5×2=10 cm/s2
(ω=ω0+αt=0+5×2=10 rad/s)
ar=rω2=2×102=200 cm/s2

Hence option D is the correct answer
