A quick projectile motion problem. Please help me Thanks

AI Thread Summary
To solve the projectile motion problem, the marble is thrown horizontally at 23.4 m/s from a height, striking the ground at a 61.8° angle. The vertical acceleration is -9.8 m/s², while the horizontal velocity remains constant at 23.4 m/s. By using trigonometric functions, specifically the tangent function, the vertical velocity component can be determined. This information can then be used to calculate the height from which the marble was thrown. Understanding that velocity is a vector and visualizing the components will aid in solving the problem effectively.

A marble is thrown horizontally with a speed of 23.4 m/s from the top of a building. When it strikes the ground, the marble has a velocity that makes an angle of 61.8 ° with the horizontal. From what height above the ground was the marble thrown?

So far I have found Ay= -9.8, Ax= 0, Vox=23.4, Voy=0. And Vx=23.4 (im not sure if I need that).

Any help will be greatly appreciated! Thank you!

remember velocity is a vector too and can be treated like distances. Draw a triangle to represent the x and y velocities. if you set it up right you should be able to use the Tan funtion to find the y velocity component. I'm sure you can figure it out from there
 

Thread 'Rolling without slipping on a curved surface'

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 .

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 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
