How much will the impulse of a car weighing 1 ton change (modulo) when its speed changes from 54 km / h to 72 km / h?

Vehicle impulse at 54 km / h:

Р1 = m * V1, where m is the mass of the car (m = 1 t = 1000 kg), V1 is the speed of the car (V1 = 54 km / h = 54 * 1000/3600 = 15 m / s).

Р1 = 1000 * 15 = 15000 kg * m / s.

Vehicle impulse at 72 km / h:

P2 = m * V2, where V2 is the vehicle speed (V2 = 72 km / h = 72 * 1000/3600 = 20 m / s).

P2 = 1000 * 20 = 20,000 kg * m / s.

Pulse change:

P2 – P1 = 20,000 – 15,000 = 5,000 kg * m / s.

Answer: The momentum of the car will increase by 5000 kg * m / s.
