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 '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 .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
