Question

An object of mass 300 kg is observed to accelerate at the rate of 4 m/s 2 . Calculate the force required to produce this acceleration

Answer 1

Answer:

F = 1200 N

General Formulas and Concepts:

Forces

Newton's Second Law of Motion: F = ma

• F is force (in N)
• m is mass (in kg)
• a is acceleration (in m/s²)

Explanation:

Step 1: Define

Identify variables

m = 300 kg

a = 4 m/s²

Step 2: Find Force

1. Substitute in variables [Newton's Second Law of Motion]:                           F = (300 kg)(4 m/s²)
2. Multiply:                                                                                                            F = 1200 N
