To determine Whether two identical automobiles have the same momentum or not. Explanation Given data: The two automobiles are identical in nature and have the same speed. One automobile travels in the east direction and other one travels in the west direction. Formula used: Write the expression for linear momentum ( p → ) of the object as follows: p → = m v → (1) Here, m is mass of the object, and v → is velocity of the object. Calculation: Consider the positive sign for the velocity of the automobile, when the automobile travels in the east direction. Consider the negative sign for the velocity of the automobile, when the automobile travels in the west direction. Consider automobile-1 travels in the east direction and the automobile-2 travels in the west direction. Calculation of momentum of automobile-1: Modify the expression in Equation (1) for the momentum of automobile-1 as follows: p → 1 = m 1 v → 1 (2) As both the automobiles are identical in nature, the mass is equal for both the automobiles. Consider the mass of each automobile as m. As both the automobiles have the same speed, consider the speed of each automobile as v . As the automobile-1 travels in the east direction, the positive sign is considered for the velocity of the autobile-1 as follows: v → 1 = + v Substitute m for m 1 , and ( + v ) for v → 1 in Equation (1) as follows: p → 1 = m ( + v ) p → 1 = m v (3) From the analysis, it is clear that, the momentum of automobile-1 is m v . Calculation of momentum of automobile-1: Modify the expression in Equation (1) for the momentum of automobile-1 as follows: p → 1 = m 1 v → 1 (2) As both the automobiles are identical in nature, the mass is equal for both the automobiles
