A hand pushes three identical bricks as shown. System A consists of two bricks stacked together. System B consists of a single brick. System C consists of all three bricks. There is friction between the bricks and the table. The bricks are moving to the left and speeding up. In the spaces provided at right, draw and label separate free-body diagrams for systems A and B. (Ignore vertical forces.) The vector representing the acceleration of system A is shown at...

Three blocks, each of mass 14 kg are on a frictionless table. A hand pushes on the left most box (A) such that the three boxes accelerate in the positive horizontal direction as shown at a rate of a = 0.6 m/s2. 1) What is the horizontal force on block A due to block B?
Three identical 6.0-kg cubes are placed on a horizontal frictionless surface in contact with one another. The cubes are lined up from left to right and a force is applied to the left side of the left cube causing all three cubes to accelerate to the right at 3.0 m/s2. What is the magnitude of the force exerted on the right cube by the middle cube in this case? a. 18 N b. none of the above c. 12 N...

Three identical disks are initially at rest on a frictionless
horizontal table..... the answer is E, please explain?
32 Three identical disks are initially at rest on a frictionless, horizontal table with their edges touching to form a triangle, as shown In the top view above. An explosion occurs within the triangle. propelling the disks horizontally along the surface. Which of the following diagrams shows a possible position of the disks at a later time? (In these diagrams, the mangle...
Three identical hockey pucks are located on a horizontal
frictionless surface as shown above. B and C are initially at rest,
and A has initial belocity 12 ft/s to the right, as shown. Given
that A hits B, and then C, that A has velocity 6 ft/s to the right
after both impacts, and that B's and C's final velocitoes both
subtend the same angle with the horizontal (X-direction), use
conservatin of Linear Momentum and Conservation fo Total Energy to...
A person holds two bricks together in one hand, pinching them as indicated by the arrows in the -figure to the left. As can be seen, the bricks have a tendency to swing apart at the bottom, contacting only at their top edges. We want to analyze the system to better understand its behavior and stability conditions (i.e. the bricks are not swinging around or falling out of the person's hand). This is done by analyzing a free body diagram...
Three identical blocks connected by ideal strings are being
pulled along a horizontal frictionless surface by a horizontal
force F⃗ . (Figure 1) The magnitude of the tension in the
string between blocks B and C is T = 3.00 N . Assume that
each block has mass m = 0.400 kg .What is the magnitude F of the force?What is the tension TAB in the string between block A
and block B?
(III) Four identical blocks (A)-) are sitting on a horizontal surface, as shown below. Different external forces are acting on each block, as shown with force vector arrows. (a) Rank the apparent weight of each block from lowest to highest. (answer: A CD B (b) Calculate the apparent weight of block D (mass 2.04 kg) if the surface is accelerating straig!ht downwards at 2.02 m/s2. (answer: 15.9 N) (c) Calculate the apparent weight of block D if the surface is...
