Question

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

Answer 1

`a_(t) = 1.216\,(m)/(s^(2))`

Step-by-step explanation:

The tangential component of acceleration is equal to the product of radius and angular acceleration:

`a_(t) = (0.152\,m)\cdot (8\,(rad)/(s^(2)) )`

`a_(t) = 1.216\,(m)/(s^(2))`
