Question

Problem 18

Answer 1

Given information

A father and his young daughter are ice skating. They face each other at rest and push each other while moving in opposite directions.

Step-by-step explanation

Step 1.

As the daughter and father are pushing each other in the opposite direction, so the horizontal force acting on the father equals to the daughter. Thus, by using Newton’s third law of motion, they exert equal and opposite horizontal force as there is no external force acting on the father and the daughter.
