Question

an object of mass 2kg is sliding with a constant velocity of 4 m/s on a fri tionless horizontal table the force required to keep the object moving with the same veocity is

Answer 1

using newtons first law the body moving with constant velocity keep on moving with same velocity unless an external force acts on it.

therefore required force is 0 newton

Answer 2

if table is frictionless then no force is require to maintain its state of motion
