Question

Problem 12

Answer 1

Given information

When an object falls freely under the influence of gravity, a net force is exerted on it by the earth. However, according to Newton's third law, an object exerts an equal and opposite force on the earth.

Step-by-step explanation

Step 1.

First, assuming mass of the freely falling object  , find the acceleration of the earth and the object. If the mass of the earth is M, then the acceleration of the earth will be determined by using Newton's laws of motion.

Acceleration of free falling object will be
