Question

Peg P is driven by the fork link OA along the curved path described by r = (2theta) m. At the instant Theta =pi/4 rad, the angular velocity and angular acceleration of the link are 3 rad/s and 1 rad/s2. Determine the magnitude of the peg’s acceleration at this point.

Answer 1

Answer 2

This should be pretty easy, you need to use\[v = r \omega, a = \frac{ v ^{2} }{ r }\]
combine these to get an equation for acceleration in terms or just r and w, then substitute in your numbers.
