Rod oa rotates with an angular velocity of latex: \dot{\theta}θ ˙ = 2 rad/s , which is increasing at latex: \ddot{\theta}θ ¨ = 0.5 rad/s2. the double collar b is pin-connected together such that one collar slides over the rotating rod and the other slides over the curved rod, of which the shape is described by the equation r = 1.5(2 - cos latex: \thetaθ ) ft. determine the radial and transverse components of the velocity and acceleration of the collar at the instant latex: \thetaθ = 120°.
