Given data:
* The mass of the van is 2400 kg.
* The acceleration of the van is,
[tex]a=3.5ms^{-2}[/tex]Solution:
According to the Newton's second law,
[tex]F=ma[/tex]where F is the resultant force, m is the mass of van and a is the accleration,
Substituting the known values,
[tex]\begin{gathered} F=2400\times3.5 \\ F=8400\text{ N} \end{gathered}[/tex]Thus, the resultant force acting on the van is 8400 N.
