∙ 13y agoThis looks like a trick question. If a boy, stationary with respect to the bus, observes a car moving relative to himself at -3 m/s, the car's velocity relative to the bus is also -3 m/s.
If your teacher disagrees, ask her when she proved Einstein's theory of relativity wrong.
It's possible the answer was intended to be -9 m/s, but if so it shouldn't have specified that the observer was in the bus.

What is variable velocity?
variable velocity can be defined as a moving body whose velocity changes with time
How is speed and velocity the same?
No, they are not the same! Velocity involves the speed and the direction of the moving object...
What is root mean square velocity?
For an object moving at a variable velocity you:calculate the square of the velocityfind its mean valuecalculate its square root.If the velocity is constant then the RMS velocity has the same value.
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
What would the acceleration of a turtle that is moving with a constant velocity of 0.25 miles per second to the right?
The acceleration would be zero because the turtle is moving at a constant speed
Why you do velocity analysis?
velocity analysis is done to check the velocity of different links moving with respect to different links.
Acceleration can be defined as the rate at wich velocity?
Acceleration is observed when velocity changes with respect to time. For instance, at t0 an object may be moving with a velocity of 2. At t1, it could be moving with velocity of 4, which means that it has doubled its velocity; thus accelerating. This can also be observed in reverse, where at t0 the velocity is 4 and at t1 the velocity is 2. The object then has decelerated, or has slowed down with respect to change in time.
What is the difference between constant velocity and variable velocity?
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
How do you get initial velocity without acceleration?
Define a moving coordinate system with respect to a stationary object.
What is velocity the same as?
Velocity is a relative term. If we call that the object is moving and in particular direction, then there must be another object present, from witch it is moving away. and we can not say, witch object is moving away. If all object maintain the same position in respect to each other then, we will call them to have zero velocity.
What is the same as zero velocity?
Velocity is a relative term. If we call that the object is moving and in particular direction, then there must be another object present, from witch it is moving away. and we can not say, witch object is moving away. If all object maintain the same position in respect to each other then, we will call them to have zero velocity.
If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
When does a cyclist appear to be stationary with respect to another moving cyclist?
when their velocity vectors are in the same direction and same magnitude
A mass m is moving with a onstant velocity parallel to x axis itts angular momentum with respect to origin is.?
Zero.
When a man moves inside a moving bus then what is the speed of man with respect to ground?
It is just the vector sum of the velocity of the bus and the man
What is the no-slip condition that all fluids satisfied?
A moving fluid will take zero velocity with respect to solid boundary when sticks with that solid surface.
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
