Abus 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?

5 300

Explanation:

Think step:

The momentum is the product of mass an velocity, that is P = mv

The law of conservation of momentum states that for an elastic collision, the sum of the momenta is zero. That is: ∑P = mv₁ + mv₂ + mv₃ + mv...

So we add the momenta like this:

mass of bus = 1.5 × 10³ kg

velocity of the bus = + 20 m/s

mass of car = 9.5 × 10² kg

velocity of car = - 26 m/s

The total momentum =
