This method it is based on the principle of momentum and the amount of movement; and used to solve problems involving strength, mass, speed and time.

If units of the SI are used, the magnitude of the impulse of a force is expressed in N * s. however, when remembering the definition of the newton.

[tex]N*S=(kg*m/s^{2} )*s = kg*m/s[/tex]

Now replacing the values on the following equation that express the definition of impulse

[tex]Impulse = Force * Time\\\\Impulse = 215 * 1.5 = 322.5 [kg*m/s][/tex]
