Tanya randhawa is standing on top of a train that is traveling at 7 km/sec. The train hits a cow and comes to a complete stop. There is no gravity or friction in Tanyas world. According to newton's first law what happens to tanya

Since there is no gravity or friction in Tanya's world, according to Newton's first law she will keep moving at a constant speed.

Explanation:

Newton's First Law, or also called the Law of Inertia, postulates that every body that is not subjected to any interaction (free or isolated body) remains at rest or moves with constant speed. In other words, it is not possible for a body to change its initial state (whether of rest or motion) unless one or more forces intervene.

In this law then the net force (Σ F) applied on a body is equal to zero and explains that to modify the state of motion of a body it is necessary to act on it.
