Just took the quiz

Answer 2

Graph A

Step-by-step explanation:

The impulse of a force F is defined as the integral of the force F over the time, t:

`J=\int\limits^(t_1)_(t_2) {F} \, dxt`

where t1 and t2 represent the time interval during which the force F is applied.

If we compare this to the graph, we see that the impulse J basically corresponds to the area under the graph of the force, F, against the time, t. So, in this case, it corresponds to choice A, which represents exactly this graph (force against time).
