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 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 of 3 meters per second to 9 meters per second in 3 seconds?
acceleration = change in velocity divided by timeaccel = (9-3)/3 = 6/3 = 2 meters per second per second
Why is acceleration often expressed with units of meters per second squared?
Because if speed is measured in meters per second (m/s) and time is measured in seconds, the SI unit of acceleration is meters per second per second (m/s2). ^_^
A car accelerates from rest at 2 meters per second per second What is its speed 3 seconds after the car starts moving?
6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
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.
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.
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
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 of 3 meters per second to 9 meters per second in 3 seconds?
acceleration = change in velocity divided by timeaccel = (9-3)/3 = 6/3 = 2 meters per second per second
How much does its speed change after 5 minutes with an acceleration of 470 meters per second?
"470 meters per second" is a speed, not an acceleration. Assuming you mean "470 meters per second square", that is the same as a change of 470 meters per second every second. Just multiply by the number of seconds to get the change in speed."470 meters per second" is a speed, not an acceleration.

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
Ignoring the effects of air resistance what is the speed in of the object after falling 3 seconds?
The speed of an object after falling for 3 seconds, ignoring air resistance, would be approximately 29.4 m/s. This value is derived from the acceleration due to gravity (9.8 m/s^2) multiplied by the time the object has been falling (3 seconds).
A car accelerates from rest at 2 meters per second per second What is its speed 3 seconds after the car starts moving?
6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
An object's velocity changes from 30 meters per second to 23 meters per second in 3 seconds What is is its acceleration?
-2.33 metres per second squared
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
