If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction).
All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.
If you know only average speed and time, you don't have enough information.You need to work with VELOCITIES - not with speeds.
And you need to know the DIFFERENCE between the final velocity and the initial velocity. Knowing the average velocity doesn't help (for a given average velocity, the acceleration could be anything).
The calculation is to divide the difference in velocity (i.e., final velocity minus initial velocity) by the time elapsed. That will give you the AVERAGE ACCELERATION.

What is the maximum acceleration of a train travelling at 90 miles per hour?
The speed or velocity of a train has no bearing on its acceleration.
What is the maximum acceleration of a train with a maximum speed of 90 miles per hour?
You have to know how long it takes to get to 90 mph to solve this. Speed = acceleration x time
How do you calculate speed without distance?
If you know the initial speed (u), acceleration (a) and time (t), then the final speed, v = u + at.
A car accelerate uniformly from 6.6 m s in 6.5 seconds whats the distance the car travels during that time?
Not enough information. You also need to know how much the acceleration is. Once you know that, calculate the final speed, then calculate the average speed as (initial speed + final speed) / 2, and multiply that by the time to get the distance.
If the plotted points on a speed time graph do not form a straight line what do you know about the objects acceleration?
You can conclude that the acceleration of the object is not constant.
How do you find average speed during acceleration?
To find the average speed during acceleration, you can calculate the average speed as the initial speed plus the final speed divided by 2. If you know the initial and final velocities, you can find the average speed over that acceleration period. Alternatively, you can use the formula: average speed = total distance traveled / total time taken.
How can I Calculate average velocity without time?
Will you settle for average speed ?The general method for solving any problem is to use what you do know in orderto find the answer. Generally, you never use something you don't know, right ?Well, you told us what you don't have, but neglected to mention what you do have.If you know starting and ending speed, then average speed = 1/2 (starting speed + ending speed).If you know distance and acceleration, then time = sqrt( 2 x distance / acceleration).Then you have time and distance, and you can find average speed.
What is the acceleration if the speed is increased to 8 meters per second?
To calculate acceleration when the speed increases to 8 meters per second, you would need the initial speed and the time it took for the speed to change. Acceleration is the rate of change of speed over time. Without knowing the initial speed or the time taken for the change, it's not possible to determine the acceleration.
What is the maximum acceleration of a train travelling at 90 miles per hour?
The speed or velocity of a train has no bearing on its acceleration.
When you know both the speed and direction of an object's while it is in motion do you know the acceleration of the object?
Not necessarily. Knowing an object's speed and direction of motion does not automatically provide information about its acceleration, which is the rate of change of velocity. Acceleration depends on how much the velocity is changing over time, which might not be evident just from knowing the initial speed and direction.
Does earth have more acceleration than a car?
No and yes. Acceleration is the action of Speeding up while speed is Distance over time. Speed yes. Acceleration. No one would ever know
What is the maximum acceleration of a train with a maximum speed of 90 miles per hour?
You have to know how long it takes to get to 90 mph to solve this. Speed = acceleration x time
How do you work out the initial speed?
To calculate initial speed (also known as initial velocity), use the following formula: initial speed = (final speed - acceleration*time). You will need to know the final speed, acceleration, and time to calculate the initial speed accurately.
How do you calculate speed without distance?
If you know the initial speed (u), acceleration (a) and time (t), then the final speed, v = u + at.
What are three important details to know about an object's motion?
Speed, Acceleration, and Position
A car accelerate uniformly from 6.6 m s in 6.5 seconds whats the distance the car travels during that time?
Not enough information. You also need to know how much the acceleration is. Once you know that, calculate the final speed, then calculate the average speed as (initial speed + final speed) / 2, and multiply that by the time to get the distance.
When you know both the speed and the direction of an object's motion you know the what?
I'm pretty sure its the acceleration. If its not that, its the Velocity.
