An impulse is applied to a moving object with a force of 10 n for 2 seconds. calculate the change in momentum of the object.

The correct answer to this question is 20 N*s.

Explanation:

To solve this problem, we must remember that impulse is equal to change in momentum.

Change in momentum = impulse

Now, we must use the equation for impulse to solve the problem.

Impulse = force * time

Next, we can just plug in the given information to find our answer.

Impulse = 10 N * 2 s

Impulse = 20 N*s

As we proved earlier, the impulse is equivalent to the change in momentum, and thus the change in momentum is equal to 20 N*s as well.

Hope this helps!

b would be the answer
