The velocity of an object increases from 5.0 m/s to 15 m/s in 2.0 s. What is the average acceleration of the object?
-10 m/s2
-5.0 m/s2
+5.0 m/s2
+10 m/s2
(15-5)m/s / 2s = 5 m/s^2
Thank you for your help
you're welcome. Just keeping track of the units helps show how to form the calculation.
To find the average acceleration of an object, you need to use the formula:
average acceleration = change in velocity / time
In this case, the change in velocity is given as the difference between the final velocity (15 m/s) and the initial velocity (5.0 m/s), which is:
change in velocity = 15 m/s - 5.0 m/s = 10 m/s
The time taken is 2.0 s.
Now, plug in these values into the formula:
average acceleration = 10 m/s / 2.0 s = 5.0 m/s^2
Therefore, the average acceleration of the object is +5.0 m/s^2.
