(change in velocity)/(change in time)=avg. acceleration
(-30 m/s)/(15s)= -2 m/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.
What is the acceleration in miles per second squared if a car is traveling 20 miles per second and takes 3 seconds to brake?
-6.667 miles per second squared
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
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 acceleration of a car that goes from 32 miles per second to 96 miles per second in 8 seconds?
Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------
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 starting on a skateboard and 10 seconds later traveling 20miles per second what is acceleration?
20 miles per second / 10 seconds = 2 miles per second ^ 2
What is the acceleration in miles per second squared if a car is traveling 20 miles per second and takes 3 seconds to brake?
-6.667 miles per second squared

If aunt Minnie drops a penny into a wishing well and it falls for 3 seconds before hitting the water How fast is it going when it hits?
30 m/s The acceleration due to gravity is 9.81 m/s2. So, after the 1st second, it is traveling 9.81 m/s. After the 2nd second, it is traveling 19.62 m/s. After the 3rd second, it is traveling about 30 m/s.
A car accelerates to pass a truck going from 20miles per second to 29miles per second in 3 seconds what was the acceleration?
So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/s2
If a train is traveling at 50 feet per second and experiences an acceleration of 10 feet per second how many seconds will it take to stop?
Well if it accelerates, it speeds up so it won't stop. If you mean decelarate, it decreases 10 ft/s every second, so 50/10 is 5 seconds
A car traveling at speed 30 meters per second and stops a break at 3.0 seconds what is the acceleration?
Just divide the speed difference by the time - a difference of 30 m/s, divided by 3 seconds, is equal to 10 m/s2.
What is the acceleration of a car that goes from 32 miles per second to 96 miles per second in 8 seconds?
Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------
How fast is your car traveling if you go 2100ft in 11 seconds?
2100 ft in 11 seconds is 190.90 ft per second. Traveling that distance in 1 second you are going 130.15 mph.
What is the acceleration of a rock that initially is traveling 1 meter per second and at the end of 30 seconds is traveling 7 meters per second?
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
