The object's instantaneous acceleration is (8t - 8) at any time.
We can't calculate the average acceleration, because you haven't defined a period
of time over which to average it. We need the start and finish times in order to
find an average.

Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
What is light's acceleration if its traveling at a constant speed of 300000 km s?
It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.
Can an object be moving when its acceleration is zero?
Acceleration, which is the change of velocity over the change in time, will equal zero when there is no change in velocity. This can occur when an object is stationary or when an object is traveling at a constant velocity.
If the acceleration is increasing with time will the velocity graph be a straight line concave up or concave down?
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.
How can you use the graph of velocity versus time to estimate the acceleration of the ball?
If the graph is a straight line, then the slope of the line is the average acceleration of the ball.
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
A car traveling in a straight line has a velocity of 5.0 ms After an acceleration of 0.75 ms squared the cars velocity is 8.0 ms In what time interval did the acceleration occur?
4.0 s
Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
Compare velocity from acceleration?
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
Can a bus change direction of its velocity when traveling with constant acceleration?
Yes, if the acceleration is not colinear with the existing velocity.
What is the acceleration of a ball that is traveling at a constant velocity of 50 meters per second and has been traveling for 2 minutes?
zero - it is constat velocity. so acceleration is zero50 m/s2 Another : The acceleration is ZERO. Acceleration is defined as the change in velocity per unit time. If the ball is traveling a constant velocity over a two minute period, the acceleration would be zero since there is no change in velocity.
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
When something is traveling at a constant velocity it has no acceleration. In other words your answer is 0.
Can an object traveling at constant velocity have acceleration why?
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
What is the acceleration of a ball that is traveling at a constant velocity of fifty miles and has been traveling for over 2 minutes?
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
What can Acceleration be found by?
Acceleration can be found by taking the derivative of a function for velocity, as acceleration is the change in velocity with respect to time.
An in-line skater traveling in a straight line goes from 3ms to 9ms in 3 s. What is the acceleration?
Calculate the difference in velocity, Then divide that by the time. The result will be the acceleration, in this case, in meters per second squared.
