Question

1. a 10 n force is applied to a 2 kg object. what is its acceleration?

7 m/s²
10 m/s²
5 m/s²
2 m/s²

Explanation:

Step1: Recall Newton's Second Law

Newton's second law is \( F = ma \), where \( F \) is force, \( m \) is mass, and \( a \) is acceleration. We need to solve for \( a \), so rearrange the formula to \( a=\frac{F}{m} \).

Step2: Substitute the given values

Given \( F = 10\ N \) and \( m = 2\ kg \), substitute into the formula: \( a=\frac{10\ N}{2\ kg} \).

Step3: Calculate the acceleration

\( \frac{10}{2}=5 \), so the acceleration \( a = 5\ m/s^2 \).

Answer:

The option with \( 5\ m/s^2 \) (the third option, e.g., if the options are labeled as A, B, C, D with C being \( 5\ m/s^2 \), then C. \( 5\ m/s^2 \))
