Question

calculate the force on an object that has a mass of 10 kg and an acceleration of 4 m/s2
40 n
0.4 n
8 n
2 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 that \( m = 10 \, \text{kg} \) and \( a = 4 \, \text{m/s}^2 \). Substituting these into the formula, we get \( F = 10 \, \text{kg} \times 4 \, \text{m/s}^2 \).

Step3: Calculate the result

Multiplying \( 10 \) by \( 4 \) gives \( F = 40 \, \text{N} \).

Answer:

A. 40 N
