Question

1. if a 5 kg object is accelerating at 2 m/s², what is the force applied to it? 5 n 10 n 15 n 20 n

Explanation:

Step1: Recall Newton's Second Law

Newton's second law states that force \( F \) is equal to mass \( m \) multiplied by acceleration \( a \), so the formula is \( F = m \times a \).

Step2: Substitute the given values

We know the mass \( m = 5 \, \text{kg} \) and acceleration \( a = 2 \, \text{m/s}^2 \). Substituting these into the formula: \( F = 5 \, \text{kg} \times 2 \, \text{m/s}^2 \).

Step3: Calculate the force

Performing the multiplication: \( 5 \times 2 = 10 \), so the force \( F = 10 \, \text{N} \).

Answer:

10 N (corresponding to the option with "10 N")
