Explanation:
In the graph of the force vs the time:
Force is the gradient of the momentum versus the time.
If we get the area under the curve in this graph:
it will be calculated as : force * time
which gives the change in momentum or the impulse.
Therefore, the area under the curve <span>represents the impulse of the force in a graph of force versus time</span>
Fnet=m*a
a= Fnet/m
a=(20N[E]+9.0N[E])/ 12.0kg
a=2.4167m/s^2
a ≈ 2.4m/s^2
The answer would be
Negative Acceleration
No. You have the units wrong.
Example with numbers:
When you multiply (1/9) by 2, you get 2/9 .
With units:
When you multiply (m/s) by (kg), you get (kg-m/s).
