a = vf - vi/Δt, where a is acceleration, vf is final velocity, vi is initial velocity, and Δt is time interval.
a = (7m/s - 1m/s)/30s = 6m/s/30s = 0.2m/s/s or 0.2m/s2

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.
A car traveling at 8 meters per second due north speeds up to 10 meters per second in the same direction If it takes the car 5 seconds to change its velocity what is the car's acceleration?
Magnitude of acceleration = (change in speed) / (time for the change) = 2/5 Acceleration = 0.4 meters per second2 north
What is the speed of a plane traveling 395000 meters in 9000 seconds?
395000 meters/9000 seconds is 43.889 meters/second
If a car is traveling 100 meters in 1400 seconds how fast is it traveling?
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
A car traveling at 25 meters a second speeds up to 40 meters a second over a period of 15 seconds what is the average acceleration of the car?
Average acceleration = (change in speed) divided by (time interval)A = (40 - 25) / 15 = 15/15 = 1 meter/sec2
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.
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.
If an initially stationary cart rolls down an incline with a measured acceleration of 2.7meters over seconds squared how far does the cart roll in 3point1 seconds?
.281 meters
What is the acceleration of a car traveling 1.2 meters long in 2 seconds?
1.2 divided by 2 seconds equals .6m/s... i think. acceleration without speeding is when you're going in circles, but you feel like you're going faster.
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)
A car traveling at 8 meters per second due north speeds up to 10 meters per second in the same direction If it takes the car 5 seconds to change its velocity what is the car's acceleration?
Magnitude of acceleration = (change in speed) / (time for the change) = 2/5 Acceleration = 0.4 meters per second2 north

395000 meters/9000 seconds is 43.889 meters/second
If a car is traveling 100 meters in 1400 seconds how fast is it traveling?
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
A car initially traveling at a speed of 16 meters per second accelerates uniformily to a speed of 20 meters per second over a distance of 36 meters what is the magnitude of her acceleration?
The car's final velocity will be 37.68 meters per second / 84.3 mph
A car traveling at 25 meters a second speeds up to 40 meters a second over a period of 15 seconds what is the average acceleration of the car?
Average acceleration = (change in speed) divided by (time interval)A = (40 - 25) / 15 = 15/15 = 1 meter/sec2
What does the slope of an acceleration-position graph indicate?
Meters/seconds squared
What is the acceleration experienced by a car that takes 10 seconds to reach 27 meters per seconds from rest?
velocity = acceleration x time 27 = acceleration x 10 acceleration = 2.7 m/sec/sec
