How Do You Calculate the Horizontal Component and Flight Time of a Baseball?

AI Thread Summary
To calculate the horizontal component of a baseball's velocity, use the formula Vx = V * cos(θ), where V is the initial speed and θ is the angle of projection. For an initial speed of 21.0 m/s at an angle of 35.0°, the horizontal component is approximately 17.1 m/s. To determine the flight time, apply the formula t = (2 * V * sin(θ)) / g, where g is the acceleration due to gravity (approximately 9.81 m/s²). This results in a flight time of about 2.1 seconds. Understanding vectors and projectile motion is crucial for solving these types of problems effectively.

A second baseman tosses the ball to the first baseman, who catches it at the same level from which it was thrown. The throw is made with an initial speed of 21.0 m/s at an angle of 35.0° above the horizontal. (Neglect air resistance.)
(a) What is the horizontal component of the ball's velocity just before it is caught?
m/s
(b) How long is the ball in the air?
s

I am completely lost how to start this problem, I do not even know what a horizontal component is! Any help is appreciated. Can someone please tell me how to start this?

Recall what you have learned about vectors. Motion in two dimensions has two components. I suggest drawing a picture of the motion of the ball; it may help you see the relationship between the forces acting on it and its path through space.
 
You can use the search button with the words 'projectile motion', and you'll find lots of useful threads.
 
Im still so confused!
 
Can someone please give me an example? Searching for projectile motion hasnt helped very much at all

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 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
