A bus and a car have an inelastic head-on collision. The bus has a mass of 1.5 × 10^3 kilograms and an initial velocity of +20 meters/second. The car has a mass of 9.5 × 10^2 kilograms and an initial velocity of -26 meters/second. What is their total momentum after the collision?

A) 2.5 × 10^3 kilogram meters/second
B) 3.0 × 10^3 kilogram meters/second
C) 5.3 × 10^3 kilogram meters/second
D) 5.8 × 10^3 kilogram meters/second
E) 6.0 × 10^3 kilogram meters/second

Respuesta :

Ok so you use the equation P=mv and then you add the two P values

its C) 5.3 × 10^3 kilogram meters/second, i got 100 on the test
