If F = 20 N acts on m = 4 kg, acceleration is:

To find the acceleration of the object, we apply Newton's Second Law of Motion. **1. Identify the Formula:** Newton's Second Law relates Force ($F$), mass ($m$), and acceleration ($a$) using the equation: $$F = m \cdot a$$ **2. Rearrange for Acceleration:** To solve for $a$, we divide both sides by $m$: $$a = \frac{F}{m}$$ **3. Substitute the given values:** - Force ($F$) = $20\text{ N}$ - Mass ($m$) = $4\text{ kg}$ $$a = \frac{20\text{ N}}{4\text{ kg}}$$ **4. Final Calculation:** $$a = 5\text{ m/s}^2$$ The acceleration of the mass is $5\text{ m/s}^2$.
