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.

The relative velocity between the observer and the object is the sum of their individual velocities. In this case, it would be 3.2 m/s (velocity of the observer) + 1.4 m/s (velocity of the object), resulting in a relative velocity of 4.6 m/s towards the observer.

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?
Yes, it is possible to move a source of sound relative to a stationary observer in such a way that there is no shift in the frequency of the sound. This can be achieved by moving the source and the observer towards or away from each other at the same velocity, maintaining a constant relative separation between them.
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 were Christian Doppler's contribution's?
Christian Doppler is best known for his discovery of the Doppler effect, which describes the change in frequency of a wave for an observer moving relative to its source. This effect is widely used in various fields, such as astronomy and medical imaging, to understand motion and velocity. Doppler's work laid the foundation for understanding how sound and light waves can be affected by relative motion.
What will be the relative velocity if two electrons approach each other?
The relative velocity of two electrons approaching each other would be the sum of their individual velocities. Given that both electrons have the same charge and mass, their velocities would be equal in magnitude but opposite in direction. This would result in a combined relative velocity of zero when they meet.
IS velocity possible in zero gravity?
Yes, velocity is possible in zero gravity. Zero gravity refers to an environment where gravitational forces are negligible, allowing objects to move freely without being pulled towards a larger mass. In the absence of gravitational forces, objects can still have velocity and move at varying speeds.
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, the Doppler Effect occurs when there is relative motion between the source of the wave and the observer. If both the source and the observer are moving at the same velocity, there won't be any change in the observed frequency of the wave.
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.
Why does an observer use a frame of reference to detect motion?
An observer uses a frame of reference to detect motion because motion is relative and depends on the observer's point of view. By using a frame of reference, the observer can establish a stationary point against which to measure an object's position and velocity. This helps in determining whether an object is in motion or at rest relative to the observer.
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?
Yes, it is possible to move a source of sound relative to a stationary observer in such a way that there is no shift in the frequency of the sound. This can be achieved by moving the source and the observer towards or away from each other at the same velocity, maintaining a constant relative separation between them.
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.
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.

What is the difference between relative velocity and absolute velocity?
Relative velocity is the velocity of an object as observed from a different frame of reference, taking into account the motion of the observer. Absolute velocity, on the other hand, is the velocity of an object with respect to a fixed reference point or system, typically the surface of the Earth or inertial space.
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.

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.
How do you calculate Doppler shift?
Doppler shift can be calculated using the formula: Δf = (fvcosθ) / c, where Δf is the Doppler shift in frequency, f is the original frequency, v is the velocity of the source or observer, θ is the angle between the velocity vector and the line of sight, and c is the speed of light. The Doppler effect occurs when there is relative motion between the source of waves and the observer, causing a shift in frequency.
