# Reaction of a frictionless plane [closed]

We know that a frictionless plane cannot resist the motion of a body over it...Bit it can apply normal force on the body.

If I stand on such a plane and throw a book forward, I would move backwards. Now, can the frictionless plane apply any impulse of force on me? What would be its direction?

• What do you mean by 'impulse of force?' – Jakob Lovern Jan 9 '18 at 17:27
• The friction-less plane is always applying a normal force on you which is why you don't fall through the plane. If there's no friction, there won't be any force in the horizontal direction. – Yashas Jan 9 '18 at 17:45
• I am saying that there is a time required by me to throw the book (suppose t) ...So,there must be an impulse of force,which is force times time or,change of momentum...If I calculate change of momentum,then which direction should I choose? – user179960 Jan 9 '18 at 18:06
• What force do you think the plane might apply? If none, why are you asking this question? – Bill N Jan 9 '18 at 22:42
