Abox has a momentum of 1.30 kg*m/s to the right. a 12.8 n force pushes it to the right for 0.218 s. what is the final momentum of the box.

4.09 kgm/s

Explanation:

Concept tested: Second Newton's law of motion

So what does the second Newton's law of motion state?

In this case;

Therefore; replacing the values of the variables in the formula;

we get;

Solving for final momentum;

      = 4.09 kgm/s

Therefore, the final momentum of the box is 4.09 kgm/s

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

it's a b and
