Bar \(A B\) is connected by pin \(C\) to slider \(D\) that slides along the fixed vertical rod \(E F\) as shown in Fig.3.28. Find the velocity and acceleration of the slider \(D\) if the bar \(A B\) rotates at a constant angular velocity of \(10 \mathrm{rad} / \mathrm{s}\) in counter-clockwise direction.
