Charles De Ga said:Homework Statement
Can someone help me to prove that scientifically my theory:
(Basketball)
The ball goes faster from point A to B if it doesn't touch the ground. That is to say, a pass at chess level is faster then a pass that rebounded one. (Always from point A to B with the same force applied)
Homework Equations
Which on is faster?
The Attempt at a Solution
I think that my theory is right.
Charles De Ga said:The chest level pass goes from the chest level of a player to the chest level of another.
Yes, the paths are different (One ball hits the ground and the other one doesn't) but the distance are the same: From one player to another. The path for the chess level pass is shorter and the path for the rebound pass longer.
The values were not specified.
So which one will be faster?
Again, thanks for your precious help.
Well, that and some common sense should provide the answer. As was said:Charles De Ga said:The path for the chess level pass is shorter and the path for the rebound pass longer.
("length" is referring to the to the path the ball travels)doppleganger said:If the lengths are are different and the speed of the ball the same, then one will travel from point a to point b in less time than the other.

However, the problem statement (as posted here) did not specify the angles that the two passes are thrown at.Ray Vickson said:If you compare tossing the ball at speed s at an angle A up from the horizontal, vs. tossing it at speed s at the same angle A down from the horizontal, the first will be "chest-level" and the second a "rebound". In the absence of friction (air and bounce friction) both would arrive at the same time, because the horizontal speeds are the same. Gravity acts vertically, so does not affect how long it takes the ball to go a certain horizontal distance (again, this in the absence of friction and inelastic bounce of the ball).

Physics is a branch of science that deals with the study of matter, energy, and their interactions. It focuses on understanding the fundamental laws and principles that govern the behavior of the physical world. Calculus, on the other hand, is a branch of mathematics that deals with the study of change and motion. It provides tools and techniques for solving problems involving rates of change, optimization, and motion.
Physics and calculus are closely related because calculus provides the mathematical framework for understanding and describing the physical world. Many fundamental principles in physics, such as the laws of motion and thermodynamics, are described using calculus. In turn, physics also provides real-world applications and examples for the concepts and techniques in calculus.
Calculus is used in physics to describe the relationship between various physical quantities, such as position, velocity, acceleration, and force. It is also used to solve problems involving rates of change, such as finding the velocity of an object at a specific time or determining the rate of heat transfer in a system. Additionally, calculus is used to derive and understand important laws and principles in physics, such as the laws of motion and the laws of thermodynamics.
Some common types of physics problems that involve calculus include problems involving motion (such as finding the position, velocity, or acceleration of an object), problems involving forces and energy (such as calculating work or determining the force required to move an object), and problems involving rates of change (such as finding the rate of heat transfer or the rate of change of a chemical reaction).
To improve your skills in solving physics/calculus problems, it is important to have a strong understanding of the fundamental concepts and principles in both subjects. You can also practice solving a variety of problems and seek help from teachers, tutors, or online resources. Additionally, developing good critical thinking and problem-solving skills can also be beneficial in approaching and solving complex problems in physics and calculus.
