A1000 kg car is moving south with a speed of 20 m/s. what is the momentum of the car? ?

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

your answer would be fusion

reserve is the answer
