To calculate the acceleration of the object, we can use Newton's Second Law of Motion:

$F = ma$

Where:

• $F$ is the force applied (in Newtons),
• $m$ is the mass of the object (in kilograms),
• $a$ is the acceleration (in meters per second squared).

Rearranging the formula to solve for acceleration $a$:

$a = \frac{F}{m}$

Now, substitute the given values:

$a = \frac{20 \, \text{N}}{5 \, \text{kg}} = 4 \, \text{m/s}^2$

Thus, the acceleration of the object is $4 \, \text{m/s}^2$.

Here are 5 related questions for further exploration:

1. What would happen to the acceleration if the force was doubled?
2. How would the acceleration change if the mass was increased to 10 kg?
3. What force is needed to accelerate a 10 kg object at $4 \, \text{m/s}^2$?
4. How does Newton's Second Law relate to weight and gravity?
5. What role does friction play in altering the acceleration of objects?

Tip: Always make sure the force and mass are in the same unit system when applying Newton's Second Law (e.g., N for force and kg for mass).
