What is the acceleration of a car along a straight-line path that increases its speed from zero to 100 kmh in 10 s?

Speed final = 100 km p h = 100 x 5/18 m/s
initial = 0 m/s
So change = 250/9 m/s
Time taken = 10 s
So acceleration = rate of change of velocity = 25/9 m/s^2

What is positive accelerations?
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
What is the acceleration of a car moving along a straight-line path that increases its speed from zero to 80 km per hour in 10 s?
8 km/h. s
What is the acceleration of a car moving along a straight line path that increases its speed from 0 to 100 km per hour in 10 seconds?
10 km per hour per second.
What is a negative slope?
Negative Slope can be your speed, position, and/or acceleration, as long as you X increases but your Y decreases.
What is the acceleration of a car moving along a straight line path that increases its speed from zero to 100 kilometers per hour in ten seconds?
If you want to have that in meters per second square, convert the speed to meters per second (divide by 3.6 in this case). Then, divide the speed by the time.
On a V-t graph how does constant acceleration appear?
On a graph of speed versus time, where time is plotted along the horizontal (X) axis and speed along the vertical (Y) axis: -- constant speed (zero acceleration) produces a straight, horizontal line; -- constant acceleration produces a straight, sloped line; the slope of the line is equal to the acceleration; -- if the acceleration is positive, the line slopes up to the right (speed increases as time increases); -- if the acceleration is negative, the line slopes down to the right (speed decreases as time increases).

What is the definition of deceleration acceleration?
Acceleration is when speed increases. Deceleration is when speed decreases.
What is the acceleration of a car moving along a straight line path that increases its speed from zero?
the car could be traveling in a straight line and slowing down (negative acceleration), speeding up (positive acceleration) or maintaining constant speed (zero acceleration).
Why speed increases if its acceleration decreases?
stamina
What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.
What determines your acceleration?
The rate that your speed increases or decreases.
What is the amount by which the speed increases in one second?
It is the acceleration.
The speed at which an object falls and the acceleration at which it falls are always the same value?
No. In a vacuum, all objects fall with the same constant acceleration, meaning that their speed constantly increases. Near the surface of the earth, the speed of any falling object increases by 32.2 feet (9.8 meters) per second every second. These numbers represent the "acceleration of gravity" at the earth's surface.
What increases speed during a given interval of time?
acceleration
What is the amount by which the speed increases in one second called?
It is the acceleration.
What is the the amount by which the speed increases in one second called?
It is the acceleration.
