Question

a cleaner pushes a 4.85 kg laundry cart in such a way that the net external force on it is 56.5 n. calculate the magnitude of its acceleration (in m/s²).

Explanation:

Step1: Recall Newton's second law

$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Solve for acceleration

$a=\frac{F}{m}$. Given $F = 56.5\ N$ and $m = 4.85\ kg$.
$a=\frac{56.5}{4.85}\ m/s^{2}$
$a\approx11.65\ m/s^{2}$

Answer:

$11.65$
