Football Throwing Problem: Solving for Horizontal Catch Distance

AI Thread Summary
To determine the horizontal distance a receiver should be from a football thrown at 20 m/s and an angle of 25°, the range formula is essential. The time the ball is in the air must first be calculated, as it directly influences the range. Substituting the initial speed and angle into the appropriate kinematic equations will yield the solution. Clarifying any specific areas of confusion is necessary for further assistance. Understanding these principles of 2D motion is crucial for solving the problem effectively.

I get the feeling this one is really easy but I am having a hard time. I am trying to figure this out but its making me go nuts. I think you might have to use the range formula but I am not 100 percent sure. thanks in advance

A football is thrown toward a receiver with an initial speed of 20 m/s at an angle of 25° above the horizontal. At what horizontal distance the receiver should be to catch the football at the level at which it was thrown?

you should really show some work before asking for help and yes this is a really easy one.

HINT: finding the time the ball is in the air is key to calculating the range.
 
You just need to substitute the given variables in the formula to find range. I don't know what is difficult here? Please make clear the part you have not understood if you want us to explain you something. We cannot read your mind, only what you write.
 
This is a qn on 2D motion, You can solve it using one of the four formulas in kinematics.. See what are the given quantities and what is it that u are finding.
 
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...
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...
