Question

An object of mass 1 kg is traveling with a constant speed of 10 m/s in the positive x-direction. Consider case 1 in which the object above comes to a stop in 1 second. Consider case 2 in which the same object comes to a stop in 10 seconds instead of 1 second.

Which case had the bigger change in momentum?

Which case had the bigger impulse?

I know impulse is J = f*(Tf-Ti) but I don't see any forces listed. The time is bigger for one but maybe the force was less? They could be the same, or it could be "not enough info"?

Answer 1

in both cases, the object has the same initial and final momentum

check the definition of impulse
