How to Solve Horizontal Projectile Questions?

AI Thread Summary
To solve horizontal projectile questions, first determine the time it takes for the stone to hit the ground using the horizontal distance and initial velocity. The vertical motion can be analyzed separately to find the height of the cliff using the time calculated. The impact velocity can be found by combining both horizontal and vertical components, taking into account the gravitational acceleration. Key equations include V = Vo + at, X = Xo + Vot + 1/2at^2, and v^2 = Vo^2 + 2a(change in)X. Understanding these principles is essential for accurately solving projectile motion problems.

Homework Statement



a person sstanding on a cliff throws a stone with a stone horizontal velocoty of 15.0m/s
and the stone lands on the ground 47.0m from the base of the cliff.

a. how much time does it take for the stone to hit the ground?
b. how high was the cliff?
c.what is the impact velocite of the stone(magnitude and derection)

Homework Equations


V = Vo + at
X = Xo + Vot + 1/2at^2
v^2= Vo^2 + 2a(change in)X

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

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...
