Inertial reference frame?

THe hallmark of an inertial rreference frame is that any object which is subject to zero net force will travel in a straight line at constant speed.To illustrate , consider the following: I am standing on a level floor at the origin of an inertial frame $ and kick a frictionless puck due north across the floor. A.)What are the x and y coordinates of the puck as a function of time as seen from my inertial frame.(Use x and y axes pointing east and north respectively.) Now consider two more observers, the first at rest in a frame $' that travels w/ constant acceleration due east relative to $.(All three frames coincide at the moment when I kick the puck, ans $'' is at rest relative to $ at that moment.) B.)Find the coordinates x', y' of the puck and describe the pucks path as seen from $'.


C.)Do the same for $''. Which of the frames is inertial?

Inertial reference frame?
it is where the point or frame where basis of observation starts





goodluck!
