AI Thread Summary
To find the horizontal distance a 1 kg mass falls from a height of 50 m while being influenced by a horizontal wind of 20 km/hr, first calculate the time it takes for the mass to hit the ground using the formula for free fall. Given that g = 9.81 m/s², the time can be determined from the height. Once the time is known, use the horizontal wind speed to calculate the distance traveled in the x direction during that time. This approach provides a straightforward method to solve the problem. The key is to combine the vertical and horizontal motions to find the final distance from the original point.

You need to post the original question...
 
sorry
i have not original question because some one ask me for this question and i sketch this image by my self .
problem is: i hold mass 1 kg then i liberate it at height 50 m .at this time have the wind blows in horizontal from the left goes to right 20km/hr . if g = 9.81m/s^ 2 . How much is this mass fall far from original point ( horizontal distance )?
 
the first place to start is how long it takes for the ball to hit the ground.
this should be very straight forward.

then use that amount of time to see how far the ball travels in the x direction in this amount of time. hint: you are given the velocity in the x direction.

Hope this helps!
 
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...
