What was the initial speed, v0, of the bullet?

To determine the initial speed, v0, of the bullet, you need to use the given information and relevant equations from physics, such as the equation for projectile motion. By analyzing the trajectory of the bullet and considering factors like distance traveled and time taken, you can calculate the initial speed of the bullet.


The Doppler effect says that if v0 is greater then vs then an observer will hear a higher pitch in front of source does that mean if vs is greater v0 an observer will hear a higher pitch BEHIND source?

Yes. vs > v0 and you're behind the source means you're catching up to it. Only the relative motion matters for the Doppler effect. Even though you're behind the source and it's moving away from you in absolute terms, you're moving toward it in relative terms.


If two automobiles have the same acceleration do they have the same velocity?

No. V=v0 +at is the formula for velocity, the acceleration 'a' can be the same but the initial velocity v0 may be different. If v0 is the same for the two automobiles , the velocity would be the same.


What does eph mean in physics?

In physics, "eph" does not have a widely recognized or standard meaning. It is possible that it could be a typo or an abbreviation specific to a certain context or school.


Do the laws of physics imply free will?

The laws of physics describe how matter and energy interact, but they do not directly address the concept of free will. Free will involves the ability to make choices and decisions independently of deterministic physical processes. The relationship between free will and the laws of physics is a philosophical and metaphysical question that remains open to interpretation.
