Given data
*The given mass of the student is m = 76 kg
*The given distance is s = 15 m
*The given time is t = 20 s
The speed of the student is calculated as
[tex]\begin{gathered} v=\frac{s}{t} \\ =\frac{15}{20} \\ =0.75\text{ m/s} \end{gathered}[/tex]The formula for the momentum of the student is given as
[tex]p=mv[/tex]Substitute the known values in the above expression as
[tex]\begin{gathered} p=(76)(0.75) \\ =57\text{ kg.m/s} \end{gathered}[/tex]Hence, the momentum of the student is p = 57 kg.m/s
