Calculate the momentum of a 1,500 kg car traveling at 6 m/s. A military airplane sometimes needs to refuel in mid-air, and another plane flies above it to add the fuel. If a plane with a mass of 7,800 kg is traveling with a velocity of 30 m/s and refuels by adding an additional 800 kg of jet fuel, what will its new velocity be? (Hint: This is a multi-step problem).

See the answers below.

Explanation:

Momentum is defined as the product of mass by velocity, in this way we have the following equation.

where:

P = momemtum [kg*m/s]

m = mass = 1500 [kg]

v = velocity = 6 [m/s]

Now we have to calculate the momentum of the plane when it travels at 30 [m/s].

Now this same momentum must be conserved, in such a way that the mass is increased but the velocity must decrease for the momentum to be conserved.
