A : A person on a frictionless surface can get away from it by blowing air out of his mouth R : For every action there is an equal and opposite reaction.

An object moves to the East across a frictionless surface with constant speed. A person then applies a constant force to the North on the object. What is the resulting path that the object takes ?

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

A person starts with a speed of sqrt((0.5gr)) at the top of a large frictionless spherical surface, and slides into the water below (see the drawing). Then , the person

Can a tug of war be ever won on a frictionless surface?

Plants do not get benefits from

A soure of sound of frequency 165 Hz generates sound waves which get fully reflected from a wall . A person standing at the wall starts moving away from the wall. The minimum distance of the point from the wall at which the person hears maximum sound is (velcoity of sound = 330 ms^(-1) )

(A) : A person can walk on a rough surface (R) : Reaction of the force applied by the man on the surface keeps him moving

A van is standing on a frictionless portion of a horizontal road. To start the engine, the vehicle must be set in motion in theforward direction. How can the persons sitting inside the van do it without coming out and pushing from behind?

The weight of a person on a plannet A is about half that on the Earth. He can jump upto 0.4 m height on the surface of the Earth. How high can be jump on the planet A ?
