What is a car's acceleration if it increases its speed from 5 meters per second to 20 meters per second in 3 seconds?
In general, the acceleration during that time interval could vary considerably. However, we can calculate the average acceleration during the interval. The change in speed is 20 meters per second - 5 meters per second = 15 meters per second, and this change in speed occurs over a 3 second interval. Thus the average change in speed over this interval is 15 meters per second/ 3 seconds = 5 meters per second per second = 5 meters/second2

What is the acceleration of a sprinter that runs a race in 12 seconds and finishes the race traveling 24 meters per second?
The sprinter's acceleration is 2 meters per second squared.
What is the acceleration of 3 meters per second to 9 meters per second in 3 seconds?
acceleration = change in velocity divided by timeaccel = (9-3)/3 = 6/3 = 2 meters per second per second
Why is acceleration often expressed with units of meters per second squared?
Because if speed is measured in meters per second (m/s) and time is measured in seconds, the SI unit of acceleration is meters per second per second (m/s2). ^_^

What is the acceleration if the velocity increases by eighty meters per second in twenty seconds?
Average acceleration = (change in speed) divided by (time for the change)= (80) / (20) = 4 meters per second2

How much does its speed change after 5 minutes with an acceleration of 470 meters per second?
"470 meters per second" is a speed, not an acceleration. Assuming you mean "470 meters per second square", that is the same as a change of 470 meters per second every second. Just multiply by the number of seconds to get the change in speed."470 meters per second" is a speed, not an acceleration.

What is the acceleration of a car that goes from 32 meters per second to 96 meters per second in 8 seconds?
Acceleration = (change in speed) divided by (time for the change)Acceleration = (96 - 32) / 8 = 64/8 = 8 meters per second2
Ignoring the effects of air resistance what is the speed in of the object after falling 3 seconds?
The speed of an object after falling for 3 seconds, ignoring air resistance, would be approximately 29.4 m/s. This value is derived from the acceleration due to gravity (9.8 m/s^2) multiplied by the time the object has been falling (3 seconds).

If a car takes 10 seconds to go from 0meters per second to 25 meters per second at constant acceleration what is the acceleration?
Acceleration = (change in speed) divided by (time for the change) = (25) / (10) = 2.5 meters per second2
