Question

Some men were trying to push a car that had run out of gas. They applied a total force of 400
N for 220 seconds.

Calculate the impulse force. (The units should be N-s.)

Information: Changing Momentum As Newton's 1" Law states, an object's velocity will not change unless a force acts on the object. Since momentum involves velocity, a force will change an object's momentum. The force that causes a change in momentum is called an impulse. An impulse may be a very quick push or a push that lasts for a long time. To calculate how much the momentum changes you need to know how long the force lasts. "A" means “change in" Ft = m(Av) Impulse Force Change in momentum F= force of impact in Newtons m = mass of the object in kg t= the time of impact, how long the impact force acts on the object Av = change in velocity of the object Before proceeding to the questions, please notice the difference between "force of impact" and "impulse force". The impulse force is actually the force of impact multiplied by the time of impact.
