Answer :
Final answer:
The magnitude of the change in the car's momentum is determined using the impulse-momentum theorem. The formula for calculating impulse, which represents change in momentum, is 'Force x Time', giving us a result of 6000 N*s in this scenario.
Explanation:
The magnitude of the change in the car's momentum can be calculated using the impulse-momentum theorem, which essentially states that the change in momentum of an object equals the impulse applied to it. In terms of physics, impulse can be considered as the change in momentum of an object when a force acts upon it for an interval of time. In this case, the force (F) is 3000N and the time (t) is 2 seconds for which the force is applied on the car.
Impulse is given by the formula: Impulse = F * t. So, here it would be:
Impulse = 3000N * 2s
= 6000 N*s.
This value represents the magnitude of the change in the car's momentum which is measured in kilogram meters per second (kg*m/s) or Newton-seconds (N*s).
