According to newton�s first law of motion, if there is no net force (unbalanced forces) acting on an object that is moving at a constant 30 mph, the object will: question 2 options: a) continue to move at 30 mph b) eventually come to a stop c) change its inertia d) accelerate.

a) continue to move at 30 mph

Explanation:

As per Newton's First law we know that if object is at rest then it will continue to be in the same state until and unless some external unbalanced force will act upon it

So here we know that

so we can say

then we have

so here we can say that momentum of the system will remain conserve if there is no force on the system

so correct answer will be

a) continue to move at 30 mph

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
