Question

a body of mass 10kg is sliding on a frictionless surface with a velocity 2m/s.What is the force required to keep it moving with a same velocity?

Answer 1

Object is moving at a velocity 2 m/s.

To keep the body moving with the same velocity, net force must be zero.

The surface on which the body is sliding is frictionless. So there is no opposing force actin on the object.

Since there is no opposing force, we do not need to apply any force. The object will keep moving at velocity 2 m/s on its own.

So your answer is: No force is required to keep it moving with same velocity.

Answer 2

Answer:

to keep the moving body with the same velocity net force must be zero so no force is required to keep it moving with the same velocity
