Question

an object experiences a net zero external unbalanced force. Is it possible for the object to be travelling with a non zero velocity? If yes, state conditions that must be placed on magnitude and direction of velocity. If no, provide reason​

Answer 1

Answer: yep

Explanation: If the net force on object is 0 then acceleration of the object is 0 which means rate of change of velocity is 0⇒the body might be in rest  or moving with constant velocity                                                                      for example , when a ball falls into a deep well it moves with constant velocity(terminal velocity) after some time because weight of ball is balanced by buoyancy and viscosity .

Answer 2

Explanation:

When a net zero external unbalanced force is applied on the body, it is possible for the object to be travelling with a non-zero velocity. In fact, once an object comes into motion and there is a condition in which its motion is unopposed by any external force; the object will continue to remain in motion. It is necessary that the object moves at a constant velocity and in a particular direction....
