# College Physics 4.3 – The acceleration of a laundry cart pushes by a cleaner

## Solution:

From Newton’s second law of motion, we know that

$\text{net Force}=\text{mass}\times \text{acceleration}$

For this particular problem, we are solving for the acceleration. Hence, the formula for acceleration is

$\displaystyle \text{acceleration}=\frac{\text{net force}}{\text{mass}}$

In symbols, that is

$\displaystyle \text{a}=\frac{\sum \text{F}}{\text{m}}$

Substituting the given values and solving for the unknown, we have

$\displaystyle \text{a}=\frac{60.0\:\text{N}}{4.50\:\text{kg}}$

$\text{a}=13.33\:\text{m/s}^2$

The acceleration of the laundry cart is about 13.33 m/s2.
