Collision Momentum: Magnitude & Direction

AI Thread Summary
The discussion focuses on calculating the total momentum of a truck and a car before their collision using vector addition. The truck, with a mass of 5750 kg and a speed of 10 m/s, has a momentum vector that can be represented in the eastward direction. The car, with a mass of 2500 kg and a speed of 25 m/s, has a momentum vector directed northward. By applying the graphical method of vector addition, the total momentum's magnitude and direction can be determined, with the final values expressed in kg·m/s and degrees counterclockwise from east. Participants are encouraged to share their calculations and any difficulties encountered during the process.

A truck with a mass of 5750 kg traveling with a speed of 10 m/s collides at right angles with a car with a mass of 2500 kg traveling with a speed of 25 m/s.



(a) Using the graphical method of vector addition, add the momentum vectors to get the total momentum of the system prior to the collision.
___magnitude____kg·m/s
___direction____° (counterclockwise from east)

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...
