Problem F12-36 Dynamics Hibbeler 13th (Chapter 12)

Peg P is driven by the forked link OA along the path described by the r = exp(theta), where r is in meters. When theta = pi/4 rad, the link has an angular velocity and angular acceleration of theta_dot = 2 rad/s and theta_dot_dot = 4 rad/s^2. Determine the radial and transversals components of the peg's acceleration at this instant.
