Do M1 ANd M3 have the same horizontal acceleration?
by jbunniii: All surfaces frictionless. And jbun deals with this Kleppner and Kolenkow exercise using the template. An example to you !said:Thread 4694028 Kleppner - Pedagogical Machine
Can you clarify this? What will cause m1 to move to the left? Is this motion in the nature of a velocity or an acceleration?LCSphysicist said:I think, inittialy the m1 block will move [just way to say] to left
Yes, before the rightward force F is applied, the pulley will be responsible for leftward force and acceleration.LCSphysicist said:[QUOTE = "jbriggs444, publicação: 6315537, membro: 422467"]
Você pode esclarecer isso? O que fará com que o m1 se mova para a esquerda? Esse movimento é da natureza de uma velocidade ou aceleração?

Well, i think that force net on the pulley. Actually i don't know if its right to think in acceleration or velocity :C
The problem you are having seems to be that in this thread, the question asks for the acceleration of the block with mass, M1, if the applied force, F, is zero. (See the Homework statement below.) Indeed, the M1 block accelerates to the left in this case.LCSphysicist said:well, so, why does the m3 block will have the net force horizontally to the left?
resolution that i find:

The problem as stated in that thread by @jbunniii :jbunniii said:I'm trying to solve this problem from Kleppner and Kolenkow:
...
The main difference between M1 and M3 is their mass. M1 is an object with a mass of 1kg, while M3 is an object with a mass of 3kg.
According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the force acting upon it and inversely proportional to its mass. Therefore, if both M1 and M3 are acted upon by the same force, M3 will have a lower acceleration due to its higher mass.
In order for M1 and M3 to have the same acceleration, they would need to be acted upon by different forces. For example, if M1 is acted upon by a force of 1N and M3 is acted upon by a force of 3N, they will have the same acceleration.
The acceleration of an object can be calculated using the equation a = F/m, where a is the acceleration, F is the force acting on the object, and m is the mass of the object. By plugging in the respective values for M1 and M3, we can calculate their individual accelerations.
Yes, the surface on which an object is placed can affect its acceleration. This is because different surfaces have different levels of friction, which can impact the force acting on the object and therefore its acceleration. However, if the surfaces are the same, M1 and M3 will still have different accelerations due to their different masses.
