Three balls are attached by rigid rods of negligible mass as seen in the diagram below. This system is placed on a table which lies in the horizontal plane (noting that the view shown below is the "bird's eye" view of the table). Balls A and B each have a mass of 0.2 kg, while Ball C has a mass of 0.8 kg. Note that the diagram is not to scale. (a) Locate the x and y coordinates of the ball and rod system's centre of mass, G, within the coordinate system shown. (b) At the instant the 10 N force is applied as shown in the diagram, calculate the instantaneous linear acceleration of the mass centre. (c) At the instant the 10 N force is applied, calculate the instantaneous angular acceleration of the ball and rod system, α.

A bar with a length of L = 0.50 m slide without friction on horizontal rails, as shown in Figure 1. There is a uniform magnetic field of B = 2.0 T directed into the plane. At one end of the rails, there is a battery with an emf of ε = 15 V and a switch. The bar has a mass of 0.90 kg and a resistance of 5.0 Ω, while any other resistance in the circuit is negligible. The switch is closed at t = 0. Figure 1 (a) Plot the speed of the bar as a function of time. (b) What is the acceleration of the bar immediately after the switch is closed? (c) What is the acceleration of the bar when its speed reaches 2.0 m/s? (d) What is the terminal speed of the bar?

The truck with a ladder plotted in Fig. 5 starts from rest (and accelerates to the left) with an acceleration of 7 m/s2. The ladder of mass m = 10 kg, which is the rigid body of interest in this problem, can be modeled as a uniform slender rod that is hinged at point A and supported at point B. As a consequence, the center of mass G of the ladder is located at the midpoint of the rod. Any friction in this problem is supposed to be small enough to be neglected. a) Determine the minimum linear acceleration amin of the truck such that the ladder loses contact at point B, i. e. the normal force NB at B vanishes, and starts to rotate about point A. Do so by determining the sum of the moments about point A, and verify that for the given acceleration of the truck, the ladder will in fact lose contact at point B. b) Determine the mass moment of inertia I¯ of the ladder associated with its center of mass G. c) Use the result found in Part b) and employ the concept of relative acceleration expressed in terms of a normal-tangential coordinate system to determine the initial angular acceleration vector α of the ladder. Figure 5: A truck with a ladder accelerating from rest to the left and measurements.
