As Per Provided Information
we have been asked to find the net force on the skateboard .
Formula Used
[tex] \bf \:Force_{net} = mass \: \times acceleration[/tex]
Put the given value we obtain
[tex]\sf\quad \dashrightarrow\:Force_{net}
= 2 \times 3 \\ \\ \\ \sf\quad \dashrightarrow\:Force_{net}
= 6kgm {s}^{ - 2} \\ \\ \\ \sf\quad \dashrightarrow\:Force_{net}
= 6N[/tex]
Therefore ,
