b. -1.92 m/s2
Minutes per second is not a unit of velocity. If the question meant meters per second, the answer is correct.

What is time interval in science?
An interval is the spacing of time. For example: I ran for an interval of 10 minutes then walked for an interval of 30 minutes. Or each car has an interval of 0.5 seconds.
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
How do you find instantaneous acceleration from 5 m s to 25 m s is 4 seconds What is the rate?
Acceleration = rate of change of speed = (change of speed) / (time interval) = (25 - 5) / 4 = 20/4 = 5 m/s2
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
What is the acceleration of an object that takes 20 seconds to change from a speed of 200 minutes per second to 300 minutes per second?
"Minutes per second" is not a unit of speed. The question is really unintelligible.
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.
Find acceleration from 0m per s to 5m per s in 4 seconds?
Acceleration = (change in speed) divided by (time interval).A = 5/4 = 1.25 m/s2
When acceleration occurs?
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)
Can bodies with different velocities have same acceleration?
Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.
What category of exercise lasts a few seconds to a few minutes?
Interval training (also called "circuit training").
Does acceleration have to be measured in seconds or can it be measured in hours or minutes?
Usually measured in seconds (m/s2), you can measure it in hours or minutes, but those units of time must be translated into seconds, ie: The turtle has an acceleration of 45meters/70minutes ; 60 seconds in one minute, 60 x 70 = 4200 seconds = 45metes/4200 seconds. Therefore the turtle can travel 45 meters every 4200 seconds.
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
If the speed of an object changes from 121ms to 98ms during a time interval of 12 s what is the acceleration of the object?
We have this equation: Velocity after = Initial velocity + (acceleration * time) So, let's plug in the numbers into this equation. 98m/s = 121m/s + (acceleration * 12seconds) So, -23 = 12 seconds * acceleration dividing 12 from both sides, the acc. is -1.92m/s/s. (Yes, those are the UNITs of acceleration. And it's negative because the object slows down. )
Find the time interval of acceleration?
You want to take your change in velocity(Final Velocity - Initial Velocity)(Vi - Vf) (8.3 m/s - 5.0 m/s = 3.3m/s). The, you divide it by your average acceleration (0.50 m/s^2) (3.3m/s ÷ 0.50 m/s^2 = 6.6 m/s) So the Final Formula is t =(Vf - Vi) ÷ a
