Expert Answer

Step 1

The system’s (Earth + apple) initial momentum is zero. When the apple falls towards the Earth, it gains momentum as the Earth’s gravitational force pulls the apple towards itself. Also, the apple applies an equally opposite force on the Earth. However, since the Earth’s mass i...
