A 1000 kg car is moving south with a speed of 20 m/s. what is the momentum of the car?

20000 kg*m/s

Explanation:

Momentum is equal to mass * velocity. So plug in 1000 kg and 20 m/s for mass and velocity respectively to get 1000*20 = 20000. Be sure you convert to the correct unit when doing future problems

Answer: 20000kg*m/s south

Explanation: Momentum is defined as the amount of movement, and it can be described by the equaton:

P = m*v

Where P is the momentum, m is the mass of the object and v is the velocity.

You can notice that the velocity is a vector (so it has a direction) and also is the momentum (it also has a direction, the same one as the velocity)

so if we have that the velocity is 20m/s south (v is a vector, so i will use south as the direction of the vector), and the mass is 1000kg, the momentum is:

P = 1000kg*20m/s south = 20000kg*m/s south
