A soccer player runs up behind a 0.450-kg soccer ball traveling at 3.20 m/s and kicks it in the same direction as it is moving, increasing its speed to 12.8 m/s. What magnitude impulse did the soccer player deliver to the ball?

To develop this problem it is necessary to use the concepts related to Impulse.

The impulse is defined as the change in velocity at the rate of mass, that is

[tex]L = m\Delta V,[/tex]

Where,

m = Mass

[tex]\Delta V =[/tex] Change in Velocity

This change in velocity can be expressed as,

[tex]L = m(v_2-v_1)[/tex]

[tex]L = 0.45*(12.8 - 3.2)[/tex]

[tex]L = 0.45*9.6[/tex]

[tex]L= 4.32 Kg.m/s[/tex]

Therefore the magnitude of the impulse is 4.32 Kg.m/s
