Question

A bus and a car have an inelastic head-on collision. The bus has a mass of 1.5 × 103 kilograms and an initial velocity of +20 meters/second. The car has a mass of 9.5 × 102 kilograms and an initial velocity of -26 meters/second. What is their total momentum after the collision? 2.5 × 103 kilogram meters/second 3.0 × 103 kilogram meters/second 5.3 × 103 kilogram meters/second 5.8 × 103 kilogram meters/second 6.0 × 103 kilogram meters/second

Answer 1

C. 5.3 × 10^3 kilogram meters/second

Answer 2

C, 5.3*10^3 kg m/s, is the correct answer to this question. Find the momentums of each object using p = mv, and then add the momentums together.
