2. (Chapter 13: Use rectangular coordinates)The sliders A and B are connected by a light rigid bar of length l = 0.5 m and move with negligible friction in the horizontal slots shown (see Figure 2). For the position where xA = 0.4 m, the velocity of A is vA = 0.9 m/s to the right. At this instant(a) draw the free-body-diagrams sliders A and B,(b) determine the acceleration of the slider B, and(c) determine the force in the bar.

We Part (a) [2 marks] The angular displacement of the rigid body ranges from θ = 0° (the vertical as shown in the figure) to θ = 135° and can be modelled using simple harmonic motion. Assuming a rate of 20 [reps/min], write down an expression for angular displacement, θ [rad] as a function of time, t [s]. You may assume that the motion starts with an angular displacement of 135°. Hint: The angular displacement, θ can be expressed as...
You provided the following answer: I don't understand why you ignore the vertical acceleration in point D? Why are you assuming that aDt = 0? I think there is a vertical acceleration in point D ... Could you explain this? 8. (25 points) Pulley A rotates with the angular velocity and angular acceleration shown.
