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

If an object goes from 60 mph to 10 mph in 5 seconds what is its acceleration?
-10 mph/sec
What does per second per second mean?
Per second per second or (/s/s) refers to the rate of acceleration. If you are standing still and you increase your speed at a rate of 5 feet per second per second that means after 1 second you'll be moving at 5 feet per second, after two seconds you'll be moving at 10 feet per second, after three seconds you'll be moving at 15 feet per second, and so on. Every second that goes by, 5 more feet per second will be added to your speed. So 5ft/s/s is a rate of acceleration. An easier example to understand, instead of per second per second, is per hour per second. If you are in a car that is standing still and you increase your speed at a rate of 5 miles per hour per second that means after 1 second you'll be traveling at 5 miles per hour. After 2 seconds your speed will have reached 10 mph. After 10 seconds you'll be traveling at 50mph. Each second that goes by you add 5mph to the speed.
If an object goes from 50 mph to 30 mph in 5 seconds what is its acceleration?
-4 mph/sec (Study Island Answer)
If you walk 10 meter in 3 second what is the walking rate?
Calculator time again! Yea! Follow along with me using your calculator please. Ok now, If you walk 10 meters in 3 seconds, how fast are you going? There are 60 seconds in 1 minute. 3 seconds goes into 60 seconds 20 times. So, 10 (meters) times 20 equals 200. In one minute you will walk 200 meters. Since there are 60 minutes in one hour, you have to multiply 200 (meters) times 60 (minutes). Go ahead, I'll wait. ...............Ok you will have walked 12,000 meters in one hour. WOW! So there are 1,000 meters in a kilometer, right? Divide 12,000 by 1,000 and you get 12. You will have walked 12 Kilometers in one hour. That's fast. the real answer is 10/3 or 3.33m/s
What is the speed of an object if it goes 20 meter in 4 seconds?
Speed = Distance/Time = 5 metres per second
Find the acceleration of a car that goes from A meters per second to B meters per second in 8 seconds?
It would be (B-A)/8
In 0.5 seconds a projectile goes from 0 to 300 meters per second What is the acceleration of the projectile?
600 m/s2 ( About 61 G's ! )
The velocity of an object goes from 4 m per second to 12 m per second in 4 seconds what is its acceleration?
The change in velocity was 8 m / s. Divide that by 4 seconds and get 2 m / s2 -- sometimes stated as acceleration of 2 meters per second per second.
What is the acceleration of a car that goes from 40 kmhr to 80 kmhr in 2 seconds?
First, convert the speeds to SI units, that is, to meters/second. Then, simply subtract the difference in speed by the 2 seconds. The result will be in meters/sec2.
The average acceleration of a car that goes 0 ms to 25 ms in 8.0 s is?
Not sure of your abbreviations. I'll assume that 'ms' = "meters per second", and 's' = "seconds" Change in speed = (25 - 0) = 25 meters per second Time = 8 seconds Average acceleration = (change in speed) / (time) = 25/8 = 3.125 meters per second2
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 goes from 0 to 120 in three seconds flat?
Something that has a constant acceleration of 13.3 per second squared
What is the average speed if a ball goes 24 meters in 0.5 seconds?
48 metres per second.
If a car goes in 6.8 seconds how do you figure out the acceleration?
Acceleration= distance / velocity squared
In 0.5 seconds a projectile goes from 0 to 300 meter per second What is the acceleration of the projectile?
600 m/s2 ( About 61 G's ! )
Definition for positive acceleration?
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)
An inline skater traveling in a straight line goes from 3ms to 9ms in 3 s. what is the acceleration?
i dont know i asked that queston please help me!!!
