Question:

Passengers on a commercial jet experience changes in horizontal force as the jet accelerates and decelerates in mid flight without changing altitude. The graph below shows the horizontal force versus time exerted on the 90000 kg jet as it accelerates from an initial velocity of 187.8 m/s to its final cruising velocity. According to the graph, what is the final cruising velocity of the jet? Show your work.

Impulse:

The sudden application of a force on a body which acts over a small time interval (dt) is termed as an impulse of the force on the body.

{eq}I = \int F. dt {/eq}

The impulse is also calculated using the change of momentum of the body within that small time interval.

In the graph, we see the variation of the horizontal force of the jet with time.

The area under the force-time graph gives us the change in momentum...
