Question

A delivery worker is pushing a heavy Loaded cart with a mass of 60 kg along a flat surface. What is the normal force acting on the cart ?

Answer 1

ANSWER:

588 N

STEP-BY-STEP EXPLANATION:

We have that the normal force is given by the following equation:

$\begin{gathered} F_N=m\cdot g\cdot\cos \theta \\ \text{where m is mass, g is gravity} \end{gathered}$

The angle that is formed with the ground is 0 degrees, because there is no inclination, therefore, we replace:

$\begin{gathered} F_N=60\text{ kg}\cdot9.8\frac{m}{s^2}\cdot\cos 0 \\ F_N=588\text{ N} \end{gathered}$
