I have a question about Kinetic and Potential Energies.

AI Thread Summary
The discussion revolves around calculating the kinetic energy gain, potential energy loss, work done against friction, and average frictional resistance for a parcel sliding down a 12-meter chute. The parcel starts from rest at a height of 3 meters and reaches a speed of 5 meters per second at the bottom. Participants express confusion about the problem and seek assistance in solving it, particularly in understanding the equations for kinetic and potential energy. The problem is framed as an inclined plane scenario, emphasizing the need for clarity in the calculations. Overall, the thread highlights the challenges faced in applying energy concepts to this physics problem.

Question: The top of a chute whose length is 12 meters is 3 meters vertically above its lowest point. A parcel of mass 1.6 Kilogram slides from rest from the top of the chute and reaches the lowest point with a speed of 5 meters per second. Calculate, for the the parcel:

(A) The gain in Kinetic Energy.
(B) The loss in Potential energy.
(C) The Work done in overcoming the frictional resistance.
(D) The average value of this resistance (force of friction).

Treat the "chute" as an inclined plane which the parcel slides down.

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 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
