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.

 

If the car’s velocity changed from 0 m/s to 1.75 m/s, calculate the mass of the car.

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.
