Ans;- 4.6 meters per second. This assumes they are heading 'Directly' towards each other, and the 'Impact speed' will be the sum of their individual speeds !. But If they are approaching each other on a collision path, but at an angle, then one of the speeds will be vectored, by trigonometry to reduce its approach speed, according to the angle.

Is it possible to move a source of sound relative to a stationary observer so that there is no shift in the frequency of the sound?
For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer
Can a body posses two velocities at a specific time?
For different observers (moving at different velocities), the object will have different velocities (relative to the corresponding observer). For one and the same observer, the body will have only one velocity at any given time.
IS velocity possible in zero gravity?
Velocity is relative to the observer and or objects that are in the area , if your sitting in true zero gravity from your point of view you will be standing still but in-reality your velocity will based on your original thrust. Some one watching you (at a zero velocity) from another location might see you zoom by at the original velocity. So the new question is if that other person has zero velocity and is in zero gravity what time will it be when they look at their watch ? Hmmm
What is the apparent velocity of a star relative to another star?
It is the a parallax.
How do you measure the true velocity of an object in the universe if the velocity of all objects in the universe are relative to each other?
If anyone ever referred to the "true" velocity of an object, he mis-spoke. All we can directly measure from the earth is an object's velocity relative to the earth. And when we have measured the velocities of several objects relative to the earth, then we can calculate the velocity of one relative to any of the others. But it's quite correct to observe that there's no such thing as the "true" or "real" velocity of anything, without reference to something else. Except for electromagnetic radiation, including light. That speed is always the same for all observers, no matter who you are, or how you're moving relative to anything else. If I'm moving north at 0.3c, and you're moving south at 0.5c, and Mr. Tompkins is moving west at 0.9c ... all relative to Dallas Texas ... and somebody in Seattle shines spotlights at all three of us, then each of us measures the light passing him at the same speed . . . 'c'. Each of us measures the same number. Makes no sense at all. But it's true.
What is the velocity at flatbottom halfpipe snowboard?
about 14meters per second
Does the Doppler Effect occur when both the source and observer are moving at the same velocity?
No. There has to be a relative velocity.
Why is relative velocity AFTER equal to Vf2 minus Vf1 but relative velocity BEFORE equal to V1 minus V2 in the coefficient of restitution formula?
relative velocity is defined as the time rate of change of one object with respect to another object.the relative velocity depends upon the observer i.e.if the velocities of two objects are same then the relative velocity also seems to be equal.
What is the principle of a contracting water bottle?
It is due to Einstein's theory of special relativity. If an observer views an object that is moving relative to him then it undergoes a length contraction. This is known as the Lorentz contraction. The contraction is by a factor of sqrt(1 - v2/c2) where v is the relative velocity between the observer and the object and c is the velocity of light.
Is it possible to move a source of sound relative to a stationary observer so that there is no shift in the frequency of the sound?
For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer
How do you explain Doppler effect?
Doppler effect generally is the change in frequency of a wave( majorly sound wave) for an observer moving relative to the source of the wave. f=[(v+vr)/(v+vs)]f0 where is the velocity of waves in the medium is the velocity of the receiver relative to the medium; positive if the receiver is moving towards the source. is the velocity of the source relative to the medium; positive if the source is moving away from the receiver.

Can a body posses two velocities at a specific time?
For different observers (moving at different velocities), the object will have different velocities (relative to the corresponding observer). For one and the same observer, the body will have only one velocity at any given time.
What is phase shifting?
Doppler shift is the observed effect to frequency or phase noted when the producer of a periodic wave and the observer of that periodic wave are moving with respect to each other. The best example of this is the apparent change in frequency of a siren when an ambulance goes past you. Another example is red shift, where the color of a receding star shifts towards the red end of the visible light spectrum due to its velocity relative to the Earth. When the propagation speed depends on the medium, such as for sound, the velocity of both the producer and observer relative to each other and to the medium must be considered. When the propagation speed does not depend on the medium, such as for light, only the velocity of producer and observer relative to each other need be considered.
'A car with a mass of 1200 kilograms is moving around a circular curve at a uniform velocity of 20 meters per second The centripetal force on the car is 6000 newtons What is the radius of the curve'?
32meters
What is movement of a stationary object?
-- acceleration = 0 -- velocity (speed and direction) exactly equal to the observer's velocity
IS velocity possible in zero gravity?
