Find the impulse of a passenger car with a mass of 1.5 moving at a speed of 36 km / h.

Given:

m = 1.5 tons – mass of a passenger car;

v = 36 kilometers per hour – the speed at which the car is moving.

It is required to determine p (kg * m / s) – the momentum of the car.

Let’s convert the units of mass measurement from tons to kilograms:

m = 1.5 tons = 1.5 * 1000 = 1500 kilograms.

Let’s convert the units of measurement of speed from kilometers per hour to meters per second:

v = 36 km / h = 36 * 10/36 = 360/36 = 10 meters per second.

Then the momentum of the car will be:

p = m * v = 1500 * 10 = 15000 kg * m / s.

Answer: the momentum of the car is 15000 kg * m / s.
