Shortly after a vinyl record (radius 0.152 m) starts rotating on a turntable, its angular velocity is 1.60 rad/s and increasing at a rate of 8.00 rad/s2. At this instant, for a point at the rim of the record, what is the tangential component of acceleration

The tangential component of acceleration is 1.216

Explanation:

Given:

Radius of turntable m

Angular velocity

Angular acceleration

For finding tangential component of acceleration,

We use rotational mechanics,

Tangential acceleration is given by,

Where angular acceleration, radius of turntable

Therefore, the tangential component of acceleration is 1.216
