Question

Find the resultant force that acts on a van of mass 2400 kg, if it accelerates at 3.5m/s^2

Answer 1

Given data:

* The mass of the van is 2400 kg.

* The acceleration of the van is,

$a=3.5ms^{-2}$

Solution:

According to the Newton's second law,

$F=ma$

where F is the resultant force, m is the mass of van and a is the accleration,

Substituting the known values,

$\begin{gathered} F=2400\times3.5 \\ F=8400\text{ N} \end{gathered}$

Thus, the resultant force acting on the van is 8400 N.
