What is its average speed during this 11 s interval?
To get average speed, just divide distance by time. In this case, you divide whatever distance an object moves during the 11 seconds, by the 11 seconds.
What is an increase of speed during a given interval of time?
Acceleration. Deceleration is a decrease of speed during a given interval of time.
Which is an increase of speed during a given interval of time?
"acceleration"
How to find acceleration?
Acceleration has two parts ... its size and its direction.To find the size (magnitude):-- pick a time interval-- measure the speed at the beginning of the interval-- measure the speed at the end of the interval-- subtract the speed at the beginning from the speed at the end-- divide that difference by the length of the time interval-- the result is the magnitude of acceleration during that time interval
An increase of speed during a given interval of time is called negative acceleration?
No, it's only the acceleration. By (-)ve acceleration ,it means retardation or deceleration..
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
What is the acceleration of a ball that starts from rest and rolls down a ramp and gains speed at 25 ms in 5 seconds?
Average acceleration during a time interval = (change in speed) divided by (time for the change) =(25) / (5) = 5 meters per second2
A motorcycle speeds up from 10 ms to 25 ms in 5 seconds What is the motorcycle's acceleration?
The average acceleration during any interval is (change in speed) divided by (time for the change).A = (25 - 10)/5 = 15/5 = 3 meters per second2

What is the equation used to calculate the accerleration of an object?
Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.
If the speed of an object changes from 121 ms to 98 ms during a time interval of 12s what is the acceleration of the object?
Average acceleration during the time interval = (change on speed) / (time for the change) =(98 - 121) / (12) = -23/12 = negative (1 and 11/12) meters per second2
Which of these is an increase of speed during a given interval of time?
positive acceleration
