Question

A block of mass \( 5 \, \text{kg} \) is placed on a frictionless surface. If a force of \( 10 \, \text{N} \) is applied to the block, what will be the acceleration of the block?

• A. \( 2 \, \text{m/s}^2 \)
• B. \( 5 \, \text{m/s}^2 \)
• C. \( 0.5 \, \text{m/s}^2 \)
• D. \( 10 \, \text{m/s}^2 \)

Hint:

Use Newton's second law: \( F = ma \) to find acceleration. The force applied is directly proportional to the acceleration for a given mass.

Answer 1

The Correct Option is A

Step 1: Use Newton's second law of motion \[ F = ma \] Where: - \( F \) is the applied force - \( m \) is the mass of the block - \( a \) is the acceleration Given: - \( F = 10 \, \text{N} \) - \( m = 5 \, \text{kg} \) Rearranging the formula to solve for acceleration \( a \): \[ a = \frac{F}{m} = \frac{10}{5} = 2 \, \text{m/s}^2 \] Answer: Therefore, the acceleration of the block is \( 2 \, \text{m/s}^2 \). So, the correct answer is option (1).
