A) 3000 m/s Every body continue to remain in it's state of motion unless it is acted upon by an external forces, this is called law of inertia. Inertiacomes from mass. Before Galileo it had been thought that all horizontal motion required a direct cause, but Galileo deduced from his experiments that a body in motion would remain in motion unless a force (such as friction) caused it to come to rest. Law of Inertia = Newton’s 1st Law of Motion An object at rest tends to stay at rest and a moving object tends to continue its uniform motion with the same speed and in the same direction unless being acted upon by an external force. Inertia is defined as the object’s tendency to continue doing what it was doing – if it was moving to continue to move and if it was resting to continue resting.
