Svetradugi [14.3K]

Answer:

666.67 kg is the mass of a car.

Explanation:

Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.

$Momentum(P)=Mass(m)\times Velocity(v)$

Mass of the car = m =?

Velocity of the car = v = 15.0 m/s

Momentum of the car = P = 10,000.00 kgm/s

$m=\frac{P}{v}$

$m=\frac{ 10,000.00 kgm/s}{15.0 m/s}=666.67 kg$

666.67 kg is the mass of a car.
