Problem
A particle of mass 1.5kg is travelling along the negative x-axis with a speed of 4ms−1. Its momentum is recorded in that coordinate system.
The positive x-direction is then redefined to be opposite to the original one.
State the new numerical value and sign of the particle’s momentum in the revised coordinate system, and briefly justify your answer.
