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.
Given data -
t = 1 sec
r = 1 cm = 0.01 m
Therefore, Tangential acceleration, a is given by-
Now, angular velocity is given by-
Therefore, radial acceleration,
