Which of these is a statement of the impulse-momentum theorem

The average force times the time of interaction equals the change in momentum

Explanation:

The impulse-momentum theorem states that impulse (equal to the average force times the time of interaction) is equal to the change in momentum:

where

I is the impulse

F is the average force

is the time of the interaction

is the change in momentum

We can demonstrate this theorem, by re-writing the force as mass (m) times acceleration (a):

The acceleration is equal to the change in velocity divided by the time interval:

And by simplifying , we get:

which is equal to the change in momentum.

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
