Part II MATH: Newton's 2nd Law states that force is affected by both mass and acceleration
(F=ma). We also learned that objects fall on Earth at the same rate. This is the acceleration due to
gravity (g = 9.8m/s²). Use this information to solve the following problems.

9. (2 points) Calculate how much force is needed to make ball fall on Earth if it has a mass of 13kg.

Answer 1

The force needed to make a ball with a mass of 13kg fall on Earth can be approximated to 127.4N using Newton's 2nd law of motion.

Step-by-step explanation:

According to Newton's 2nd Law of Motion (F = ma), the force needed to make a ball with a mass of 13kg fall on Earth can be calculated. We know that the acceleration due to gravity on Earth is approximately 9.8m/s². Therefore, we can use the equation F = m * g, where F is the force, m is the mass, and g is the acceleration due to gravity.

By substituting the given values into the equation, we have F = 13kg * 9.8m/s². Evaluating this equation gives us a force of approximately 127.4N. Therefore, approximately 127.4 Newtons of force is needed to make the ball fall on Earth.
