What is the acceleration of a car that maintains a constant velocity of 100km per h for 10 seconds?
Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
What is the acceleration of a car with a steady velocity of 100 km per hour for 100 seconds?
If velocity is steady and doesn't change, then there is 0 acceleration.
What is the acceleration of a inline skater going straight and goes from 3 miles to 9 miles in 3 seconds?
The acceleration cannot be determined with this information. The beginning and ending velocity needs to be known. You can determine her average velocity, however. average velocity = displacement/time = (9mi - 3mi)/3s = 6m/3s = 2m/s
If a runner increases velocity from 2 ms to 4 ms over a period of W seconds what is her acceleration?
Average acceleration over a certain time period is the difference in velocity, divided by the time. In this case, (4-2)/W.

If a car goes in 6.8 seconds how do you figure out the acceleration?
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
How do you calculate acceleration between 6 and 9 seconds?
To calculate acceleration between 6 and 9 seconds, you need to find the change in velocity during that time interval and then divide it by the time taken. The formula for acceleration is acceleration = (final velocity - initial velocity) / time. Plug in the velocities at 6 seconds and 9 seconds into the formula to get the acceleration.
When acceleration occurs?
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
Can bodies with different velocities have same acceleration?
Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
What is the acceleration of a car with a steady velocity of 100 km per hour for 100 seconds?
If velocity is steady and doesn't change, then there is 0 acceleration.
What is the vehicles velocity after 1.0 seconds?
That depends on its initial velocity and its acceleration. V1 = V0 + a * t
A sprinter explodes out of the starting block with an acceleration pf 2.3 ms2 which she sustains for 1.2 sThenher acceleration drops to zero for the rest of the raceWhat is her velocity at1.2s?
The sprinter's velocity at 1.2 seconds can be calculated using the formula: velocity = initial velocity + acceleration × time. Given the initial velocity is 0 m/s, acceleration is 2.3 m/s^2, and time is 1.2 seconds, the velocity at 1.2 seconds would be 2.76 m/s.
How long is Tina in the air when she leaps straight up with a speed of 1.8ms?
To find out how long Tina is in the air when she leaps straight up with a speed of 1.8 m/s, you can use the formula: time = velocity/acceleration due to gravity. However, since Tina is leaping straight up, her initial velocity is 0 m/s, and only the acceleration due to gravity affects her motion. The acceleration due to gravity is approximately 9.8 m/s^2. Therefore, Tina will be in the air for approximately 0.18 seconds.
Find the acceleration of a car that goes from A meters per second to B meters per second in 8 seconds?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Given the initial velocity (A), final velocity (B), and time (8 seconds), you can substitute the values into the formula to find the acceleration.
What is the velocity of the ball 0.6 seconds after its release?
To determine the velocity of the ball 0.6 seconds after its release, we need more information such as the initial velocity and acceleration of the ball. You would use the formula: velocity = initial velocity + (acceleration * time).
