Question

Find the acceleration of a \(2\) kg block acted upon by a net force of \(10\) N.

• A. \(2\ \text{m/s}^2\)
• B. \(5\ \text{m/s}^2\)
• C. \(10\ \text{m/s}^2\)
• D. \(20\ \text{m/s}^2\)

Hint:

Always remember Newton's second law: \(F = ma\). If force and mass are known, acceleration is simply \(a = \frac{F}{m}\).

Answer 1

The Correct Option is B

Concept: According to Newton's Second Law of Motion, \[ F = ma \] where

• \(F\) = net force acting on the body
• \(m\) = mass of the body
• \(a\) = acceleration produced

Thus, \[ a = \frac{F}{m} \]
Step 1: {Write the given values.} \[ F = 10\ \text{N} \] \[ m = 2\ \text{kg} \]
Step 2: {Substitute into the formula.} \[ a = \frac{F}{m} \] \[ a = \frac{10}{2} \] \[ a = 5\ \text{m/s}^2 \]
Step 3: {State the final result.} Hence, the acceleration of the block is \[ 5\ \text{m/s}^2 \]
