AI Thread Summary
In the discussion about two balls dropped from a building, it is established that both balls experience the same vertical acceleration of 9.81 m/s², regardless of their drop timing. Ball A, dropped first, will hit the ground before Ball B, which is dropped one second later. As time progresses, the difference in their velocities increases because Ball A has a head start. However, the distance between the two balls does not remain constant; it increases as Ball A accelerates faster due to its earlier drop. The need for clear explanations and calculations in solving these physics problems is emphasized.

Due in 10 Minutes PART TWO ! (Two balls dropping from roof) True/False

Homework Statement



Ball A is dropped from the top of a building. One second later, ball B is dropped from the same building. Consider the balls while they are both in flight. You may ignore air resistance. Which statements are true about this situation?
As time progresses, the difference between their accelerations increases
Ball A will hit the ground before ball B
Both have the same vertical acceleration
As time progresses, the difference between their velocities increases
As time progresses, the distance between them stays constant

Homework Equations


The Attempt at a Solution



1. False, acceleration is constant 9.81
2. True, it fell first
3. True, acceleration is constant
4. Hm. I say true? One started accelerating first so the velocity should increase faster than the other
5. False, wouldn't it increase because the velocity on one is greater?Please help!

Again, you need to show working and not just guess the answers!
 


Done. Quick! Help! hehe
 


#4 - they have the same acceleration (you said this yourself), so why should A's velocity increase at a greater rate (i.e. have greater acceleration) if they're supposed to be the same?

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
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...
