Question

A cleaner pushes a 4.50-kg laundry cart in such a way that the net external force on it is 60.0N. Calculate its acceleration.

Answer 1

We can find the acceleration of the laundry cart from the Newton's Second Law of Motion:

$$F_{net} = ma,$$

here, $F_{net} = 60.0 N$ is the net external force acting on the cart, $m = 4.50 kg$ is the mass of the cart and $a$ is the acceleration of the cart.

Then, from this formula we can calculate the acceleration of the laundry cart:

$$a = \dfrac{F_{net}}{m} = \dfrac{60.0 N}{4.50 kg} = 13.3 \dfrac{m}{s^2}.$$

Answer:

$a = 13.3 \dfrac{m}{s^2}.$
