The Frozen Lake
You wake up on a frozen lake in an isolated region. The surface of the lake is frictionless and no grip of any kind can be attained over it. You find just your mobile phone in your pocket, but when you take it out to call for help, you realize there is no reception.
If there is no wind force to help you escape, what are you going to do to avoid freezing to death?
SOLUTION
Throw your phone as hard as you can. Thanks to Newton’s third law of motion and the frictionless lake, you will start sliding away.
