AI Thread Summary
To solve the projectile problem with given parameters (d=30, v=22, g=9.8, y0=2), the key is to analyze the motion along the x- and y-axes independently. The user is attempting to find the launch angle theta, but is struggling with the equations. A suggested approach involves using the formula for projectile motion on uneven ground, which simplifies the analysis. It is important to break down the problem into horizontal and vertical components to find the correct angle. Understanding these principles will help in determining the required angle for the projectile.

Homework Statement



Hi to all guys i am not good in physics and trigonometric I tried to do a projectile system.My launch point is higher than target point.I know the velocity v, target_distance d, gravity g,Launch_height_y y0.I added a image that shows the equation.I tried my own but not solved the equation.Please some one help me

d = 30,v = 22 , g = 9.8 ,y0 = 2

I wants to find the theta(angle)

Not sure how you got the equation but ut would be best to analyse along the independent x- and y-axes.One is accelerated and other is simple non-accelerated one.
 
Of course it is right. What I meant was analysis along x- and y-axes separately is much simpler(that's how they got the formula).

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...
