Question

a particle starts moving with constant velocity v=2 m/s from position x=5m.The position time graph will be????

Answer 1

the correct one is (c) , we have seen that any p-t graph where the velocity is constant the graph gives a straight line, here in option (a) the position is given as -5, as we know that displacement is a scalar quantity and hence cannot be negative , looking at option (b) the graph shows a negative velocity so the option (b) can possibly be correct but if the question said that the vehicle has returned to its initial position ( displacement = final - initial )
coming to option (c) the graph gives a straight line as said earlier, it clarifies that the velocity is constant, and also the starting point to be 5m
