A particle has a mass of 9.2E-7 kg and is traveling at a speed of 208993 km/s (the speed of light is 300,000 km/s).
What is the momentum of the particle?
Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
