Solving for the Horizontal Component of Velocity in a Jetliner Moving at 390 m/s

AI Thread Summary

To find the horizontal component of a jetliner's velocity moving at 390 m/s with a vertical component of 37.4 m/s, the Pythagorean theorem is applicable. The equation involves calculating the square root of the sum of the squares of the total velocity and the vertical component. The correct approach is to isolate the horizontal component using the formula: horizontal velocity = √(total velocity² - vertical component²). The calculation results in a horizontal component of approximately 392 m/s. This confirms the use of Pythagoras in solving for the horizontal component of velocity.

Hwk. Problem?

A jetliner is moving at a speed of 390 m/s. The vertical component of the plane's velocity is 37.4 m/s. Determine the magnitude of the horizontal component of the plane's velocity.

What equation would I use to solve this problem?

Am I on the right track...

Take square root of 390^2 + 37.4^2= 392 m/s

That looks like Pythagoras to me!

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 'Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?'

Here is what I tried This question was actually asked in one of our engineering entrances. The answer was 1D. My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.

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...
