Typical Relativity Car and Ball Problem.... ....

In summary, the conversation discusses the concept of relative velocity and how it applies to a car and a baseball moving in the same direction. The equations used to determine the velocities are also mentioned. The conversation also addresses the expectation of receiving answers on a problem-solving website.

The Attempt at a Solution


(a) The person outside of the car will see the car's velocity as being c/√2 and the baseball's velocity as c/√2, therefore the observer in frame S will see those two velocities as added together because they both move in the positive x-direction.
(b) Car's velocity - ball's velocity = 0 *edit* now I think this answer might be -c/√2
(c) I have no idea

(a) so what did you do to get the answer, and what did you get ?
(b) so what did you do to get the answer 0 and why do you now think it's wrong ?
(c) which equations apply ?

We have thousands of members who would disagree with your assessment.

If you've come here thinking that if you post a problem we tell you the answer, you are mistaken. We are happy to help you with your problems, and steer you in the right direction, but we won't spoonfeed the answers to you.

What is the typical relativity car and ball problem?

The typical relativity car and ball problem is a thought experiment that explores the principles of relativity and how they apply to objects moving at high speeds. It involves a car traveling at a constant velocity and a ball being thrown in the air inside the car.

What is the purpose of the typical relativity car and ball problem?

The purpose of the typical relativity car and ball problem is to demonstrate how the laws of physics, specifically relativity, can differ depending on the observer's frame of reference. It challenges our understanding of space, time, and motion.

What are the key concepts involved in the typical relativity car and ball problem?

The key concepts involved in the typical relativity car and ball problem include the principle of relativity, time dilation, and the relative motion of objects. It also explores the concept of simultaneity and how it can be perceived differently by different observers.

What are some variations of the typical relativity car and ball problem?

There are several variations of the typical relativity car and ball problem, including changing the speed of the car, the direction of the ball's throw, and the position of the observer. Some variations also involve multiple observers and the use of a stationary reference frame.

What are the real-world applications of the typical relativity car and ball problem?

The typical relativity car and ball problem has real-world applications in fields such as astrophysics and space travel, where objects are moving at high speeds and relativity must be taken into account. It also has implications for GPS technology, as the satellites must account for time dilation due to their high speeds.
