Physics problem with masses and pulley and a ramp

AI Thread Summary
To solve the physics problem involving two masses connected by a pulley, it's essential to apply Newton's second law (F=ma) to determine the system's acceleration and the tension in the cord. The tension in the rope is a reaction force resulting from the weights of the masses, and a free body diagram can help visualize the forces acting on each mass. The pulley and cord primarily serve to redirect and transmit these forces without adding mass. A clear understanding of the forces involved will allow for the calculation of both acceleration and tension. Analyzing the components of the weights acting on the rope is crucial for deriving the correct equations.

Homework Statement



2 masses m1=50g and m2=5g are connected as shown (sori walang pci) m1 is free to move along a horizontal frictionless table. Neglecting the mass of the cord connecting the two masses and assuming a frictionless pulley. Determine the accelereation of the system of blocks and tension in the cord

Homework Equations



F=ma
W=mg

The Attempt at a Solution



Force of the tension
Acceleration

I really couldn't get how to get the tension when its coming from a pulley
please help :D

The tension is just the reaction over the rope due to the force exerted by the weight of the masses. The tension over the rope is equal to the force exerted by the weights over the cord. You just need to make a diagram of free body, and analyze which components of the weights are acting over the rope in each case, and then make the sum.

You didn't put a picture, so I'll draw one as I think the problem is, I'm not sure, but I think this is it.

The cord and the pulley only acts to redirect and transmit the forces.

Can you go on from here?

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
