Answer:
<em>J=600 kg m/s
</em>
Explanation:
<u>Impulse And Momentum
</u>
Suppose a particle is moving at a certain speed and changes it to . The impulse J is equivalent to the change of linear momentum. The momentum can be computed by
The initial and final momentums are given, respectively, by:
Thus, the change of momentum is
It's equal to the Impulse J
Our data is
