Answer 2

Answer:

Newton three laws of motion may be stated as follows:

Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.

Force equals mass times acceleration [  ].

For every action there is an equal and opposite reaction.

So,    F=dtdP

But   P=mv

So,    F=dtd(mv)

Or   F=mdtdv

⟹ F=ma
