A disc rotates about its axis with a constant angular acceleration of

4 \mathrm{~rad} / \mathrm{s}^2.

Find the radial and tangential accelerations of a particle at a distance of

1 \mathrm{~cm}

from the axis at the end of the first second after the disc starts rotating.

View answer and explanation

Correct option: A

16 \mathrm{~cm} / \mathrm{s}^2, 4 \mathrm{~cm} / \mathrm{s}^2

Option A (

16 \mathrm{~cm} / \mathrm{s}^2, 4 \mathrm{~cm} / \mathrm{s}^2

) is correct because it correctly calculates the radial and tangential accelerations using the given angular acceleration and radius.
