Acceleration = change in velocity/time
a = (v - u) /t
where a= acceleration, v= velocity, u= initial velocity & t= time.
u = 121 m/s
v = 98 m/s
t = 12 m/s
a = (98 - 121) /12
a = -23/12
a = -1.91667 m/s2

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
Is the velocity of an object changes from 65 ms to 98 ms during a time interval of 12 s what is the acceleration of the object?
2.75 m/s
If the speed of an object changes from 121 ms to 98 ms during a time interval of 12 s what is the acceleration of the object?
-1.92 m/s2
Which of these is an increase of speed during a given interval of time?
positive acceleration
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 average acceleration during the time interval 0 seconds to 10 seconds?
The average acceleration during the time interval from 0 to 10 seconds is the change in velocity divided by the time interval. If you provide the initial and final velocities during this time interval, we can calculate the average acceleration for you.
How do you calculate acceleration between 6 and 9 seconds?
To calculate acceleration between 6 and 9 seconds, you need to find the change in velocity during that time interval and then divide it by the time taken. The formula for acceleration is acceleration = (final velocity - initial velocity) / time. Plug in the velocities at 6 seconds and 9 seconds into the formula to get the acceleration.
What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?
The acceleration of the ball is constant during any time interval where the velocity changes. At the moment the ball has zero velocity, the acceleration is the same as it was during the time interval when the velocity was changing. This can be calculated using the formula acceleration = change in velocity / change in time.
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

What increases speed during a given interval of time?
acceleration
Which is an increase of speed during a given interval of time?
Acceleration is an increase in speed during a given interval of time. It is the rate of change of velocity with respect to time.
What is an increase of speed during a given interval of time?
Acceleration is an increase in speed during a given interval of time. It measures how quickly an object's velocity is changing. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed).
What is An increase of speed during a given interval of time is called negative acceleration?
Actually, an increase in speed during a given interval of time is called acceleration, not negative acceleration. Negative acceleration, also known as deceleration, refers to a decrease in speed over time.
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
