Question

You are on a frictionless horizontal plane. How can you get off if no horizontal force is exerted by pushing against the surface?

• A. By jumping
• B. By splitting or sneezing
• C. By rolling your body on the surface
• D. By running on the plane

Answer 1

The correct option is B By splitting or sneezing

While splitting or sneezing you will exhale things out with some momentum by applying force on it and in return you will experience a force in the opposite direction according to the $Newto{n}^{\prime }sThirdLawofMotion$.So, in this way you will aquire a velocity on a frictionless surface and you will be able to get off it.
