Answer:
Impulse = 103 kg m/s
Explanation:
As we know that impulse is defined as change in momentum
So here we will have
[tex]Impulse = P_f - P_i[/tex]
here final speed is 5 m/s after he use his foot while his initial speed is given as 4 m/s
now we will have
[tex]P_f = 103 \times 5[/tex]
initial momentum is given as
[tex]P_i = 103 \times 4[/tex]
now impulse is given as
[tex]Impulse = (103 \times 5) - (103 \times 4)[/tex]
[tex]Impulse = 103 kg m/s[/tex]
