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

Step 1: Understanding the Question:
The problem involves determining the motion of an object given its mass and the resultant force acting on it.
This is a direct application of classical dynamics.
Step 2: Key Formula or Approach:
Newton's Second Law of Motion:
\[ F = ma \]
Rearranging to solve for acceleration:
\[ a = \frac{F}{m} \]
Step 3: Detailed Explanation:
Given:
Net Force (\(F\)) = 10 N.
Mass (\(m\)) = 2 kg.
Substitute the values into the rearranged Newton's second law formula:
\[ a = \frac{10}{2} \]
\[ a = 5\ \text{m/s}^2 \]
Step 4: Final Answer:
The acceleration of the block is \(5\ \text{m/s}^2\).
