How to find the momentum of a body if the mass is 15 kg and the time is 3 s?

To find the momentum of the body, you need to multiply the mass by the speed, i.e. P = m * V. P = 15 kg * 3 m / s = 45 kg * m / s. If the speed is in kilometers, be sure to convert to meters. If the mass is in tons, it must be converted to kilograms. The unit of measurement for impulse is kilogram per meter per second.
