What is the average velocity of a car that accelerates from 15 meters per second to 25 meters per second in 10 seconds?
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
What is the acceleration of a car that accelerates from 44ms to 88ms over a period of 11 seconds?
Average acceleration = (change in speed) / (time for the change) = (88 - 44) / (11) = 4 meters per second2
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
What is the speed of a skateboarder who accelerates from rest for 3 seconds down a ramp at an acceleration of 5 mss?
Speed = (initial speed) plus (acceleration) x (time) = 0 + (5) x (3) = 15 meters per second.
An eagle accelerates from 15 meters per second to 22 meters per second in 4 seconds. What is the eagle's average acceleration?
Average acceleration is the amount of acceleration per unit of time that a thing or an object undergoes. It is simple to discover. To find the average acceleration, we need only find out how much acceleration occurred and over what period of time. If we have the starting and the ending speeds, then by subtracting them we can find the chane of acceleration. Then we can divide that acceleration by the time it took to occur. The eagle in our example accelerates from 15 m/s to 22 m/s over a period of 4 seconds. His total acceleration was 7 m/s (22 m/s minus 15 m/s = 7 m/s), and, since it took 4 seconds to increase his speed by 7 m/s, the average acceleration is the total acceleration divided by the time it took to happen (as was stated). The average acceleration is 7 m/s divided by 4 seconds or 1.75 meters per second.

A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car’s acceleration is blankmeters/second2?
The acceleration of the body is 3 m/s²
How many meters does a car travel that starts from rest and accelerates for 4.7 seconds with an acceleration rate of 3.6 meters per second squared?
60.912 meters in that time
What is the acceleration of a car moving in a straight line at a constant rate of 29 meters per second for 4 seconds?
"Constant rate" implies there is no acceleration - acceleration is zero.
A car accelerates to pass a truck going from 20 meters per second to 29 meters per second in 3 seconds What is the acceleration?
3 m/s2
What is the acceleration of a car that accelerates from 44ms to 88ms over a period of 11 seconds?
Average acceleration = (change in speed) / (time for the change) = (88 - 44) / (11) = 4 meters per second2
To pass a truck a car initially traveling 25 meters per second accelerates at a constant rate of 3 meters per second squared after 6 seconds how fast is the car traveling?
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
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
What is the speed of a skateboarder who accelerates from rest for 3 seconds down a ramp at an acceleration of 5 mss?
Speed = (initial speed) plus (acceleration) x (time) = 0 + (5) x (3) = 15 meters per second.

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)
What is the equation used to calculate the accerleration of an object?
Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.
