Expert Solution
Introduction:
Disclaimer: “Since you have asked multiple question, we will solve the first question for you. If you
want any specific question to be solved then please specify the question number or post
only that question.”
First law of motion says that if object is at rest or in state of uniform motion, it keeps on its same state until and unless external force is applied. Here, net force on puck is zero. So the acceleration is also zero. We know that the displacement for uniform motion is given by
Where are velocity and time respectively.
