The rated power of the engine is 120km. The mass is 1.5 times 10 to the fourth power kg. The contact area between each track and the ground is 1.25m square. (g = 10N / kg)

What do you want to ask? If it's to find the ground pressure P = f / s 1.5 * 10 quartic power * 10 / 1.25 M2 = 12 * 10 quartic power n / m2
