Almost. Fix your first equation using cupid.callin's hint.drastice said:m2g-t=m2a
t=m1a
Luckily you have two equations.but i am missing acceleration and tension so how do i solve when i have 2 unknowns?
cupid.callin said:you sure tension on m2 till be just T ?
and use the hint of question to find the acceleration of the blocks
That's a different problem. In your problem there's a pulley attached to the falling mass. Get the idea, don't just copy the equation.drastice said:i'm not sure what you mean by that.. I'm looking at the link he gave me using the horrizontal pulley... Is this not the right equation?
We are helping. (But we're not going to do it for you.)i don't see why you guys can't help me with the right equation
No.and for acceleration m2*gravity/m1+m2 = acceleration right??

No.
Don't skip steps. Fix your equation for the falling mass. Then you can solve for the acceleration and tension.
Doc Al said:What are all the forces acting on m2? Each rope segment applies its own tension.
You don't 'add it' to the equation, you use it to come up with a correct equation. The approach is always the same: ΣF = ma.drastice said:it has gravity and tension from both ropes..
I have no idea how to add this to the equation though.
i just don't understand that equation.. You're not doing the problem for me be helping me with an equation... ;[
A pulley is a simple machine that helps to redirect and distribute forces in a system. In the case of 2 masses connected by a pulley, the pulley helps to distribute the tension force between the two masses, allowing for a more balanced and efficient transfer of forces. This results in a smoother acceleration for both masses.
In a system with a pulley, the tension in the rope is directly related to the acceleration of the masses. If the tension increases, the acceleration of the masses also increases. Similarly, if the tension decreases, the acceleration decreases.
The mass of the pulley does not directly affect the tension and acceleration in a system with two masses. However, a heavier pulley may increase the overall mass of the system, which can affect the acceleration due to the force of gravity acting on the masses.
Yes, a pulley can increase the acceleration of the masses in a system by reducing the amount of friction and distributing the tension force more evenly. This results in a more efficient transfer of forces, allowing for a greater acceleration of the masses.
Yes, there are some limitations to using a pulley in a system with 2 masses. The pulley must be strong enough to support the masses and the tension force between them. Additionally, the rope or string used in the system must also be strong enough to withstand the tension force. If these limitations are not met, the pulley may fail and the system will not function properly.
