A disc rotates about its axis with a constant angular acceleration of 4 rad/s2. Find the radial and tangential accelerations of a particle at a distance of 1 cm from the axis at the end of the first second after the disc starts rotating.

t = 1 sec, r = 1 cm = 0.01 m
= 4 rd/s2
Therefore ω= αt = 4 rad/s
Therefore radial acceleration,
An =ω2r = 0.16 m/s2 = 16 cm/s2
