Answer:
Below!
Explanation:
To calculate the average acceleration you can use this formula....
acceleration = finalvelocity - initial velocity / time
Because the object begins at rest we know that our initial velocity is 0 m/s
Our final velocity is 7 m/s, and our time is 0.1 seconds....
Plugging in our values :
acceleration = 7m/s - 0.1 m/s / 0.1 s
= 7 m/s / 0.1s
= 70 m/s^2
This is already at the proper amount of sig figs so we're good to go!
Therefore the average acceleration of this object is 70 m/s^2
Hope this helps! Best of luck <3
- Initial velocity=u=0m/s
- Final velocity=v=7m/s
- Time=t=0.1s
[tex]\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}[/tex]
[tex]\\ \sf\longmapsto Acceleration=\dfrac{7-0}{0.1}[/tex]
[tex]\\ \sf\longmapsto Acceleration=\dfrac{7}{0.1}[/tex]
[tex]\\ \sf\longmapsto Acceleration=70m/s^2[/tex]
