Question

what force is required to accelerate a body with a mass of 15 kilograms at a rate of 8 m/s²? a) 23 kg b) 23 n c) 120 n d) 1.875 kg

Explanation:

Step1: Recall Newton's second law

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

Step2: Identify given values

Mass \( m = 15 \) kg, acceleration \( a = 8 \) m/s².

Step3: Calculate the force

Substitute the values into the formula: \( F = 15 \, \text{kg} \times 8 \, \text{m/s}^2 = 120 \, \text{N} \).

Answer:

C) 120 N
