In attempting to pull a 1500-kg car out of a ditch, Arnold exerts a force of 300 N for three seconds, Bob exerts a force of 500 N for two seconds, and Cecil exerts a force of 200 N for four seconds. Who provided the greatest impulse?

Respuesta :

Answer:

So Bob provide maximum impulse to the car

Explanation:

As we know that impulse is defined as change in momentum

so here we have

[tex]F = \frac{\Delta P}{\Delta t}[/tex]

[tex]F\Delta t = \Delta P[/tex]

so here we can say that

[tex]impulse = F\Delta t[/tex]

1), Arnold exerts a force of 300 N for three seconds,

So impulse due to force of Arnold

[tex]Impulse = 300 \times 3[/tex]

[tex]Impulse = 900 Ns[/tex]

2). Bob exerts a force of 500 N for two seconds,

So impulse due to force of Bob

[tex]Impulse = 500 \times 2[/tex]

[tex]Impulse = 1000 Ns[/tex]

3). Cecil exerts a force of 200 N for four seconds.

So impulse due to force of Cecil

[tex]Impulse = 200 \times 4[/tex]

[tex]Impulse = 800 Ns[/tex]
