A boy is running towards a plane mirror with a speed of 25cmsecWhat is the relative velocity of this image with respect to the boy?

ou start out 25cm from the mirror: the image is 50 centimeters away. One second later, when your nose hits the mirror, the image is right on top of you--0 centimeters away. So in one second, the image traveled 50 centimeters with respect to you--thus the speed is 50 centimeters per second, or 50 cm/s.

What is the definition of final velocity?
Final velocity is the your last velocity traveled. Example if you travel 50m/s your final velocity is 50m/s because its the last velocity traveled, 0m/s is the initial velocity. Its not your total velocity because if u start running at 5m/s then accelerated 25m/s, your final velocity is NOT 30m/s. It is 25m/s. Also, your velocity change is 20m/s(25-5).
Why is a greater amount of force needed to accelerate a truck than a jeepney even if they are running with the same velocity?
The truck has a greater mass and therefore a greater amount of inertia to overcome. To accelerate a greater mass requires a greater force.
What is dual starter?
There is no such type of starters. But we can always configure dual(or multi) start & stop option as per our needs in respect to remote access of motors running. We can do it with the help of simple ms1 relay and few logics(no & nc) including a control transformer.
What is the momentum of a 12 kg dog running at 8 ms?
The momentum of a 20 kilogram dog running at a speed of 8 meters per second is 160 (kg m/s). P=mv P=momentum m=mass v=velocity The units are (kg m/s). P=mv P= 20kg x 8 m/s P= 160 (kg m/s) .
How is the gerund used in the sentence?
A gerund functions as a noun, as the subject of a sentence or a clause, and as the object of a verb or a preposition. Examples:Fishing is my dad's hobby. (subject of the sentence)I need the workout that swimming provides. (subject of the relative clause)We enjoyed the dancing in the parade. (direct object of the verb 'enjoyed')He'll need new shoes for running. (object of the preposition 'for')
Would you rather collide with someone walking running or standing still?
The energy involved is what causes harm; and that depends on the relative velocity.
What is one example of velocity?
One example of Velocity is that if you are running in the same direction, your speed and velocity is the same. But if you are running AROUND the track, your speed is the same but your velocity is changing.
What would be the velocity of ball which is thrown by the man who running at the speed equal to the velocity of light?
As velocity never exceeds the velocity of light.... so i hope a man running with the velocity of light will not be able to throw a ball with any velocity.......... we may get the maximum n minimum velocity with which that can be thrown mathematically that we may get it to be zero................

What is best to say about a runner that is running at a constant velocity?
You can say that the runner is maintaining a steady speed and is not accelerating or decelerating. This means the runner is covering the same distance in the same amount of time with each stride.
Is it possible to run round an oval running track at constant velocity?
Yes, it is possible to run around an oval running track at a constant velocity if the runner maintains a consistent speed without accelerating or decelerating. The runner would need to adjust their pace in the curved sections to counteract the change in direction and maintain a constant velocity.
The ability of running water to erode a surface depends on?
Power and Velocity.
What is the best to say about a runner who is running at a constant velocity?
The runner is maintaining a steady speed and covering equal distances in equal time intervals.
What is best to say about a runner who is running at a constant velocity?
Their acceleration is zero.
Is a person running in a circular track at 7mph an example of constant velocity at zero acceleration and if so why?
Yes, a person running in a circular track at a constant speed of 7mph is an example of constant velocity and zero acceleration. While the person is changing direction, their speed remains constant, resulting in a steady velocity. Acceleration would only occur if there were a change in speed or direction.
How if velocity calculated if a person is running with the wind?
exactly the same as if they were running against the wind, with crosswind or in a vacuum. m/s2
What is the difference between stream deposition and changing running water velocity?
