Rank the following situations according to the magnitude of the impulse of the net force, from largest value to smallest value. in each situation a 1000-kg automobile is moving along a straight east–west road. the automobile is initially : (i) moving east at 25 m> s and comes to a stop in 10 s; (ii) moving east at 25 m> s and comes to a stop in 5 s; (iii) at rest, and a 2000-n net force toward the east is applied to it for 10 s; (iv) moving east at 25 m> s, and a 2000-n net force toward the west is applied to it for 10 s; (v) moving east at 25 m> s; over a 30-s period, the automobile reverses direction and ends up moving west at 25 m> s.

Explanation:

The impulse is equal to the change in momentum of the object involved, so we can calculate the change in momentum in each situation and compare them all.

Taking always east as positive direction, and labelling

u the initial velocity

v the final velocity

m = 1000 kg the mass (which is always equal)

We find:

(i)

u = 25 m/s

v = 0

(II)

u = 25 m/s

v = 0

(III)

In this case,

F = 2000 N is the force

is the time

So the magnitude of the impulse is

(IV)

F = 2000 N is the force

is the time

So the magnitude of the impulse is

(V)

u = 25 m/s

v = -25 m/s

So the ranking from largest to smallest is:

V

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
