Hi so here is a question we have and here is the answer for it, i understand everything up until the circled part i am really stuck there so if you could just use alot of words when you explain it because our professor just puts the equation in without explaining it so please explain it as much as you can because i really dont understand it i would really appreciate it. Thank you
2 An object of uniform thickness has a cross-section as shown in the diagram. All the cubes have the same size and mass. The object is placed carefully on a smooth table. You may assume that the center of mass of the cubes to the left of Q is located on the dashed line 1, while the center of mass of the cubes to the right of Q are located on dashed line 2. When let go the object will: Obe stable and not topple. O topple to the left about the edge at P. O topple to the right only when given a very small push. O topple to the left only when given a very small push. O topple to the right about the edge at Q.
Choose the correct letter We can apply the laws of conservation of linear momentum and angular momentum to the description of the motion of rigid bodies because A. Forces that maintain constant distances between different pairs of point masses are internal forces (i.e. forces of constraint) B. Forces of constraint come in pairs and obey Newton’s third law (i.e. they are equal and act along the same line of action) C. In any displacement the relative distances and the orientations of different particles remain the same with respect to each other D. No network is done by the internal forces or the forces of constraint E. All of the above are correct F. None of the above is correct

stimulus for track questions A track is shown in the shape of a 45- 45-90 triangle with smooth corners. A 1 kilogram bead is shown moving with a constant speed (8 m/s) on this track. Two points of interest are indicated as "A" and "B". B 45 8 m/s 45 Previous Direction Key 1 The "direction key" shows eight arrow directions labeled 1 to 8. To use the "direction key", consider the vector mentioned in each question. Match the direction of the vector with the arrow in the key that best shows the direction of the required vector. For example the initial velocity vector of the object has direction "3" in the key. 2 --00 Calculate the direction of the average acceleration of the object moving from point "A" to point "B". Use the direction key to choose a direction that best represents the answer. 1 O 2 3 O4 O 5 6 O 7 O 8 O o Next
