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?

So Bob provide maximum impulse to the car

Explanation:

As we know that impulse is defined as change in momentum

so here we have

so here we can say that

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

So impulse due to force of Arnold

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

So impulse due to force of Bob

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

So impulse due to force of Cecil

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
