No, this will give you the net force acting on the 2nd block, not the force of block 2 on block 3. Instead, once you calculate the acceleration, you must draw a Free Body Diagram (FBD) which isolates the last (2.87 kg) block, identify the forces acting on that block, and apply Newton's laws to that block to solve for the force of block 2 on block 3.talaroue said:
Correct.talaroue said:
no it didn't, it gave you the net force acting on block 1
you mean you subtracted the net force from the 13.8 to get the force of block 2 on block 1.
The concept of "3 blocks on a frictionless surface" is a physics problem that involves three blocks of different masses placed on a surface with no friction. This setup allows for the study of the forces and motion of the blocks without the interference of frictional forces.
The absence of friction in this scenario means that there are no forces acting against the motion of the blocks. This allows the blocks to move without any external force slowing them down, resulting in a constant velocity.
In this scenario, there are two main forces acting on the blocks: the force of gravity and the normal force. The force of gravity pulls the blocks towards the ground, while the normal force from the surface pushes the blocks upwards to counteract the force of gravity.
The mass of the blocks affects their motion by determining the amount of force needed to accelerate them. The greater the mass of the block, the more force is needed to move it at a certain velocity. In this scenario, the blocks with larger masses will require more force to reach the same velocity as the blocks with smaller masses.
Studying "3 blocks on a frictionless surface" allows scientists to understand the relationship between forces, mass, and motion. It also helps in understanding the concept of inertia, as the blocks will continue to move at a constant velocity unless acted upon by an external force. This scenario is also useful in studying the laws of motion and their applications in real-world situations.
