The time it takes to execute this maneuver is [ 200 / (average of 40 and 80) ] = [ 3 and 1/3 ] seconds.
Acceleration = (change in speed) / (time for the change)
= 20/(3 and 1/3) = 20/(10/3) = 20 x (3/10) = 60/10 = 6 meters/sec2 = about 0.61 G

What is the average acceleration of a car that changes speed from 0 meters per second to 15 meters per second in 5seconds?
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
What are the units of acceleration?
Acceleration is a change in velocity per unit of time. Velocity is distance (d) per unit of time (t). That makes acceleration distance per unit of time squared, or something like this:We have distance/time2, or d/t2Distance is commonly measured in meters, and time in seconds. This makes acceleration appear in meters per second per second, or meters per second squared, or m/sec2.m/s2meters per second squared
A skater increases her speed uniformly from 2.0 meters per second to 7.0 meters per second over a distance of 12 meters The magnitude of her acceleration as she travels this 12 meters is?
5.0 meters every second.
Why are the units for acceleration meters per second?
Acceleration is not measured in meters/second. Meters/second is a unit of speed. Since acceleration is defined as change of speed divided by time, the units are meters/second/second, usually written as meters/second2.
What is the average acceleration of a car that changes speed from 0 meters per second to 15meters per second in 5 second?
Average acceleration = (change in speed) divided by (time for the change) =(15 - 0) / (5) = 15/5 =3 meters per second2
In what units is acceleration expressed a newtons b foot pounds c kilograms d meters per second squared?
Assuming you want the international units: time: second velocity: meters / second distance: meters acceleration: meters / second2

What is a speedboat's acceleration if its speed uniformly from twenty meters per second to thirtyone meters per second in a distance of 210 m?
.052 meters per second or .09 per meter
Why are the units for acceleration meters per second?
Acceleration is not measured in meters/second. Meters/second is a unit of speed. Since acceleration is defined as change of speed divided by time, the units are meters/second/second, usually written as meters/second2.
What is expressed in meters per second per second?
It is acceleration that is measured in distance per unit of time per unit time, or in meters per second per second, as the question asked. The only thing missing is the direction vector.
What is the average acceleration of a car that changes speed from 0 meters per second to 15meters per second in 5 second?
Average acceleration = (change in speed) divided by (time for the change) =(15 - 0) / (5) = 15/5 =3 meters per second2
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
How far will you travel in 30 seconds accelerating from rest at 1 meter per second per second?
-- Your speed after 30 seconds will be 30 meters per second.-- Since your acceleration is constant, your average speed during the 30 secondsis the average of your initial and final speed . . . 15 meters per second.-- The distance you cover is your average speed for 30 seconds = 15 x 30 = 450 meters.
If a car starts from rest and after 6 seconds it is moving at 42 ms what is the car's average acceleration?
If a car is moving 42 meters per second after 6 sectons, the average acceletion is 7 meters per second per second. It is an average, given two points of data, and it is not the instantaneous acceleration at any point in time.
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
