Bat and mirror relativistic problem is my solution good ?

[irrehaare]

So the bat is flying with velocity 172 m/s and he see himself in mirror which is parallel to the direction of fly. He can himself in the mirror because he send a sound signals with velocity 344 m/s. So now i have to count angel to the direction of motion.
a) first in arrangement of air
b) in arrangement of bat.

So here is my solution:
answer
a) cos alfa
b) sin beta

is it correct I'm not sure with arrangement

Sorry for replying so late, but I really can't read your PDF. I suspect that's why no one responded to this. If you're still interested in discussing the problem, then can you either post a better scan or show your steps in LaTeX?

of air

I would say that your solution is a good start, but there are a few things that need to be clarified. First, it would be helpful to have more information about the setup of the problem, such as the distance between the bat and the mirror, and the angle at which the bat is flying. This information can affect the calculations and the final answer.

Secondly, it's important to note that the speed of sound in air can vary depending on factors such as temperature and humidity. So the value of 344 m/s may not be accurate for all situations. It would be helpful to specify the conditions under which this value was obtained.

Lastly, in order to fully solve the problem, we would need to know the angle at which the bat is flying in relation to the mirror. This would affect the calculation of the angle to the direction of motion.

Overall, your solution shows a good understanding of the concept of relative motion and the use of trigonometric functions to calculate angles. However, more information and clarification is needed to ensure the accuracy of the solution.
