Question

What is the acceleration of a body of mass 4 kg when a force of 20 N is applied to it?

• A. 2 m/s\textsuperscript{2}
• B. 4 m/s\textsuperscript{2}
• C. 5 m/s\textsuperscript{2}
• D. 10 m/s\textsuperscript{2}

Answer 1

The Correct Option is C

Step 1: Use Newton’s second law of motion \[ F = ma \Rightarrow a = \frac{F}{m} \] Step 2: Substitute the values \[ a = \frac{20\ \text{N}}{4\ \text{kg}} = 5\ \text{m/s}^2 \] \[ \boxed{a = 5\ \text{m/s}^2} \]
