a Given that the mass of the truck is 5m, moves along a curve having radius of, 5r and the speed of the truck is 5v.
The formula of the net force is
[tex]F=\frac{mv^2}{r}[/tex]Here, m is the mass, v is the speed and r is the radius.
Substituting the values of a truck in the net force formula, we get
[tex]\begin{gathered} F=\frac{5m\times(5v)^2}{5r} \\ =\frac{25mv^2}{r} \end{gathered}[/tex]
