A classical mechanics problem by sandeep vankala

Classical Mechanics Level 1

A body of mass 25kg is released in a place (air)were there is no air resistance and zero gravity.Then the body is given an initial velocity of 4m/s.Will the body stop after some time?

Cant Be Detemined Yes No None of these

Since there is no gravitational field within the surrounding spacetime of the 25kg mass, it doesn't accelerate anywhere and stays arrested in place where the mass was released.

Upon giving it an initial velocity, since the mass is in a vacuum (no air, so no air resistance), the mass will continue to move in the direction that it was given the initial velocity. This is also known as Newton's First Law: The law of Inertia.

wasnt it necessary to mention dat d surface is frictionless?

so vat kind??? its imp to mention dat its frictionless floor

Here 0 gravity means no accelaration. and given initial velocity 4 m/s so the case is constant velocity. so body never stop....

height or distance from ground should be given

And there is nothing for it to hit into

LAW OF INERTIA : everything tends to be in motion or at rest until an external force is applied on it...and there is no force in this case :)
