What quantity has changed velocity or speed for a car that travels north at 88 kmh and then turns east while continuing to move at 88 kmh?

The speed of the car has not changed. What has changed is the direction of travel. Velocity is a combination of speed and direction, so has changed. Newton's laws say that a body will continue to travel at its starting velocity unless acted on by an external force. There are two forces working here. 1 a force reducing the northward speed of 88 km/h to zero, and 2 a force accelerating the car eastward up to 88 km/h.

Evaluate whether the velocity of a jogger can be determined from the information that the jogger travels 2 km in 10 min?
No , because velocity is a vector quantity and it needs direction.
What are the differences between speed and velocity?
Speed is distance divided by the time taken Velocity is distance in a particular direction divided by the time taken. Velocity is a vector quantity while speed is a scalar quantity. That means that velocity include information about the direction of movement, while speed does not.
A car has a mass of 20000kg and travels at 10000ms what is its velocity?
You mean, travels at 10000 m/s.....if so...Its velocity is 10000m/s
Does change in the velocity of an object always indicate a change in speed?
speed=distance divided by time........Hewitt describes it as how fast something moves; the distance an object travels per unit of time; the magnitude of velocity !!... and velocity is the speed of an object and its direction of motion ; a vector quantity. SO .....YES!!!!!!!!!!!
What measures speed and direction an object travels?
velocity
What is the distance than an object travels ina given time?
speed or velocity = distance/time Speed does not require direction, i.e. it is a scalar quantity. Velocity does require direction, i.e. it is a vector quantity.

Does Light have a speed or a velocity speed of light or velocity of light?
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
What is the different betwen distance and valocity?
Distance is a finite quantity of space between two points of reference or object. Velocity is the "speed" at which an object or particle travels along a path.

What is the plane's velocity if it travels 100 km in 90 minutes?
The definition of velocity, or at least speed, is distance/(time at speed), in this instance 10/9 km/min. (In advanced mathematics, "velocity" is a vector quantity, with both a magnitude and a direction. In that instance, a direction would also be needed but was not stated in the problem.)
What do you need know to find an objects velocity?
The distance it travels in a caertain amount of time as well as the direction
What is velocity of a wave?
How quickly the wave travels

What does velocity tell you about a moving object?
Velocity tells you what speed a moving object travels at and in what direction.
What is group velocity?
The official definition for the word group velocity is "the speed at which the energy of a wave travels."
