Impulse is equal to change in momentum. So if impulse is 2000 then to solve for new velocity we just set it equal to equation for momentum.
First find original momentum by p=mv
p=1000*20=20000
So then taking that value minus the impulse since it was in opposite direction of original momentum it will slow it down some. To find new velocity we just take
20000-2000=18000=mv
v=18000/1000 =18m/s
Hope this helps!! Any questions please ask!!
Thank you!
Density
DENSITY is the similar factor that contributes to the formation of surface currents and deep currents.
Explanation:
While salinity and temperatures affected ocean currents, they do so by affecting one property of the ocean waters that form the deep water and surface water currents. This is density. The warmer the oceans waters, the less dense they become hence they upwell to become surface currents (and vice versa). The more concentrated, with salts, the ocean waters are, the denser they become hence sink to become deep oceans currents (and vice versa).

Julia walks from the park, which is six blocks east of her house, to the store, which is three blocks east of her house. Julia walks for 5 minutes. This walk's average speed will be 1.2 blocks per minute. Option B is correct.
<h3>What is displacement?</h3>
Displacement is defined as the shortest distance between the two points. Distance is the horizontal length covered by the body. While displacement is the shortest distance between the two points.
Displacement is a vector quantity .its unit is m.
The average velocity on this walk will be;
Hence option B is correct.

Frequency, , is defined as the rate of rotation, or the number of rotations in some unit of time. Angular frequency, , is the rotation rate measured in radians. These three quantities are related by f = 1 T = ω 2 π .
