A2498 kg car is moving at 17.1 m/s slams on its brakes and slows to 2.6 m/s. what is the magnitude (absolute value) of the impulse the car experiences during this time?

J=36221 Kg.m/s

Explanation:

Impulse-Momentum Theorem

These two magnitudes are related in the following way. Suppose an object is moving at a certain speed and changes it to . The impulse is numerically equivalent to the change of linear momentum. Let's recall the momentum is given by

The initial and final momentums are, respectively

The change of momentum is

It is numerically equal to the Impulse J

We are given

The impulse the car experiences during that time is

J=-36221 Kg.m/s

The magnitude of J is

J=36221 Kg.m/s
