Question

Car A has a mass of 1.200 kg and is traveling at a rate of 22 km/hr. Car B has a mass of 1200 kg and is traveling in the
same direction at 25 km/hr. Which of the following statements is true?
Both cars have the same momentum
Car A has a greater momentum than car B.
Car B has a greater momentum than car A

Answer 1

Answer:

Car B has a greater momentum than car A

Explanation:

Given data:

Mass of car A = 1200 Kg

speed of car A = 22 km/hr

Mass of car B = 1200 Kg

speed of car B = 25 Km/hr

Solution:

For car A:

p = mv

p = 1200 Kg × 22 km/hr

p = 26400 kg.km/hr

For car B:

p = mv

p = 1200 Kg × 25 km/hr

p = 30,000 kg.km/hr
