Given: A massless particle revolving in a circle with a rotational velocity = (2+sin(a))(adsbygoogle = window.adsbygoogle || []).push({});

To Find: Y-axis acceleration

Method #1 (from rotational acceleration)

Y-axis acceleration = (2+sin(a))(cos(a))^2

Method #2 (from Y-axis velocity)

Y-axis acceleration = (2+sin(a))(cos(a))^2-(sin(a))(2+sin(a))

Which Y-axis acceleration is correct and why?

Can someone explain this?
