The value of each question is noted in parenth ... eses in the left margin. Note: The answer areas will expand to fit the length of your response. 1. Identify and explain if one of the objects in each of these pairs has a greater value for the magnitude of its momentum than the other. (No calculations should be required.) (1) a. a 900.0-kg truck travelling at 60 km/h, or a 500.0-kg car travelling at 60 km/h Answer: Since both vehicles have the same velocity, the truck with the higher mass will have higher momentum. (1) b. a 15.0-kg object travelling to the right at 5.0 m/s, or a 15.0-kg object travelling to the left at 5.0 m/s (1) c. a 900-kg truck at rest, or a 500-kg car at rest (1) d. a 900-kg truck at rest, or a mosquito flying at 2 m/s [Show More]
